Bayesian Active Exploration: A New Frontier in Artificial Intelligence
The field of artificial intelligence has seen tremendous growth and advancements in recent years, with various techniques and paradigms emerging to tackle complex problems in the field of machine learning, computer vision, and natural language processing. Two of these concepts that have attracted a lot of attention are active inference and Bayesian mechanics. Although both techniques have been researched separately, their synergy has the potential to revolutionize AI by creating more efficient, accurate, and effective systems.
Traditional machine learning algorithms rely on a passive approach, where the system receives data and updates its parameters without actively influencing the data collection process. However, this approach can have limitations, especially in complex and dynamic environments. Active interference, on the other hand, allows AI systems to take an active role in selecting the most informative data points or actions to collect more relevant information. In this way, active inference allows systems to adapt to changing environments, reducing the need for labeled data and improving the efficiency of learning and decision-making.
One of the first milestones in active inference was the development of the "query by committee" algorithm by Freund et al. in 1997. This algorithm used a committee of models to determine the most meaningful data points to capture, laying the foundation for future active learning techniques. Another important milestone was the introduction of "uncertainty sampling" by Lewis and Gale in 1994, which selected data points with the highest uncertainty or ambiguity to capture more information.
Bayesian mechanics, on the other hand, provides a probabilistic framework for reasoning and decision-making under uncertainty. By modeling complex systems using probability distributions, Bayesian mechanics enables AI systems to quantify uncertainty and ambiguity, thereby making more informed decisions when faced with incomplete or noisy data. Bayesian inference, the process of updating the prior distribution using new data, is a powerful tool for learning and decision-making.
One of the first milestones in Bayesian mechanics was the development of Bayes' theorem by Thomas Bayes in 1763. This theorem provided a mathematical framework for updating the probability of a hypothesis based on new evidence. Another important milestone was the introduction of Bayesian networks by Pearl in 1988, which provided a structured approach to modeling complex systems using probability distributions.
While active inference and Bayesian mechanics each have their strengths, combining them has the potential to create a new generation of AI systems that can actively collect informative data and update their probabilistic models to make more informed decisions. The combination of active inference and Bayesian mechanics has numerous applications in AI, including robotics, computer vision, and natural language processing. In robotics, for example, active inference can be used to actively explore the environment, collect more informative data, and improve navigation and decision-making. In computer vision, active inference can be used to actively select the most informative images or viewpoints, improving object recognition or scene understanding.
Timeline:
1763: Bayes' theorem
1988: Bayesian networks
1994: Uncertainty Sampling
1997: Query by Committee algorithm
2017: Deep Bayesian Active Learning
2019: Bayesian Active Exploration
2020: Active Bayesian Inference for Deep Learning
2020: Bayesian Active Learning for Computer Vision
The synergy of active inference and Bayesian mechanics is expected to play a crucial role in shaping the next generation of AI systems. Some possible future developments in this area include:
- Combining active inference and Bayesian mechanics with other AI techniques, such as reinforcement learning and transfer learning, to create more powerful and flexible AI systems.
- Applying the synergy of active inference and Bayesian mechanics to new areas, such as healthcare, finance, and education, to improve decision-making and outcomes.
- Developing new algorithms and techniques that integrate active inference and Bayesian mechanics, such as Bayesian active learning for deep learning and Bayesian active exploration for robotics.

Things That Are Hard
Some things are harder than they look. Some things are exactly as hard as they look.
Game AI, Intelligent Opponents, Intelligent NPCs
As you already know, "Game AI" is a misnomer. It's NPC behaviour, escort missions, "director" systems that dynamically manage the level of action in a game, pathfinding, AI opponents in multiplayer games, and possibly friendly AI players to fill out your team if there aren't enough humans.
Still, you are able to implement minimax with alpha-beta pruning for board games, pathfinding algorithms like A* or simple planning/reasoning systems with relative ease. Even easier: You could just take an MIT licensed library that implements a cool AI technique and put it in your game.
So why is it so hard to add AI to games, or more AI to games? The first problem is integration of cool AI algorithms with game systems. Although games do not need any "perception" for planning algorithms to work, no computer vision, sensor fusion, or data cleanup, and no Bayesian filtering for mapping and localisation, AI in games still needs information in a machine-readable format. Suddenly you go from free-form level geometry to a uniform grid, and from "every frame, do this or that" to planning and execution phases and checking every frame if the plan is still succeeding or has succeeded or if the assumptions of the original plan no longer hold and a new plan is on order. Intelligent behaviour is orders of magnitude more code than simple behaviours, and every time you add a mechanic to the game, you need to ask yourself "how do I make this mechanic accessible to the AI?"
Some design decisions will just be ruled out because they would be difficult to get to work in a certain AI paradigm.
Even in a game that is perfectly suited for AI techniques, like a turn-based, grid-based rogue-like, with line-of-sight already implemented, can struggle to make use of learning or planning AI for NPC behaviour.
What makes advanced AI "fun" in a game is usually when the behaviour is at least a little predictable, or when the AI explains how it works or why it did what it did. What makes AI "fun" is when it sometimes or usually plays really well, but then makes little mistakes that the player must learn to exploit. What makes AI "fun" is interesting behaviour. What makes AI "fun" is game balance.
You can have all of those with simple, almost hard-coded agent behaviour.
Video Playback
If your engine does not have video playback, you might think that it's easy enough to add it by yourself. After all, there are libraries out there that help you decode and decompress video files, so you can stream them from disk, and get streams of video frames and audio.
You can just use those libraries, and play the sounds and display the pictures with the tools your engine already provides, right?
Unfortunately, no. The video is probably at a different frame rate from your game's frame rate, and the music and sound effect playback in your game engine are probably not designed with syncing audio playback to a video stream.
I'm not saying it can't be done. I'm saying that it's surprisingly tricky, and even worse, it might be something that can't be built on top of your engine, but something that requires you to modify your engine to make it work.
Stealth Games
Stealth games succeed and fail on NPC behaviour/AI, predictability, variety, and level design. Stealth games need sophisticated and legible systems for line of sight, detailed modelling of the knowledge-state of NPCs, communication between NPCs, and good movement/ controls/game feel.
Making a stealth game is probably five times as difficult as a platformer or a puzzle platformer.
In a puzzle platformer, you can develop puzzle elements and then build levels. In a stealth game, your NPC behaviour and level design must work in tandem, and be developed together. Movement must be fluid enough that it doesn't become a challenge in itself, without stealth. NPC behaviour must be interesting and legible.
Rhythm Games
These are hard for the same reason that video playback is hard. You have to sync up your audio with your gameplay. You need some kind of feedback for when which audio is played. You need to know how large the audio lag, screen lag, and input lag are, both in frames, and in milliseconds.
You could try to counteract this by using certain real-time OS functionality directly, instead of using the machinery your engine gives you for sound effects and background music. You could try building your own sequencer that plays the beats at the right time.
Now you have to build good gameplay on top of that, and you have to write music. Rhythm games are the genre that experienced programmers are most likely to get wrong in game jams. They produce a finished and playable game, because they wanted to write a rhythm game for a change, but they get the BPM of their music slightly wrong, and everything feels off, more and more so as each song progresses.
Online Multi-Player Netcode
Everybody knows this is hard, but still underestimates the effort it takes. Sure, back in the day you could use the now-discontinued ready-made solution for Unity 5.0 to synchronise the state of your GameObjects. Sure, you can use a library that lets you send messages and streams on top of UDP. Sure, you can just use TCP and server-authoritative networking.
It can all work out, or it might not. Your netcode will have to deal with pings of 300 milliseconds, lag spikes, package loss, and maybe recover from five seconds of lost WiFi connections. If your game can't, because it absolutely needs the low latency or high bandwidth or consistency between players, you will at least have to detect these conditions and handle them, for example by showing text on the screen informing the player he has lost the match.
It is deceptively easy to build certain kinds of multiplayer games, and test them on your local network with pings in the single digit milliseconds. It is deceptively easy to write your own RPC system that works over TCP and sends out method names and arguments encoded as JSON. This is not the hard part of netcode. It is easy to write a racing game where players don't interact much, but just see each other's ghosts. The hard part is to make a fighting game where both players see the punches connect with the hit boxes in the same place, and where all players see the same finish line. Or maybe it's by design if every player sees his own car go over the finish line first.

Gerald: I've deduced that we're in some kind of temporal anomaly. Therefore I thought it better to not interact with too many elements to prevent a paradox from occurring. I'll continue to study the anomaly.
Shadow: actually, Professor, your study of the anomaly has already shaped the timeline. The Bayesian interpretation of quantum mechanics contends that the agent and the subject cannot be divorced from each other. The participation of the agent, or observer, that is to say: you, collaborates with the universe to create the universe. And if the universe were entirely material and wholly deterministic, there would be no room for free wi---

The Merits of Speculation
Tumblr media
In today’s scientific culture, there is a strong emphasis on caution. One is not supposed to go out on a limb, to make assumptions without solid grounding, and certainly not to speculate without hard data. This attitude has undoubtedly led to great successes — it protects against wishful thinking, avoids dogma, and helps describe the world in as objective a manner as possible. But it also has a shadow side: it can stifle thought, constrain imagination, and discourage the mind from exploring new territories.
It should be acceptable to entertain hypotheses — even if the starting points are uncertain or even questionable. Take, for instance, the idea that consciousness causes the collapse of the wave function. As a Bayesian, I can never be really sure this is true. In fact, I’m not even entirely convinced that “consciousness” is a well-defined concept, or that quantum mechanics is the ultimate language of physics. And yet: if I take the idea seriously, just for a moment, just as a thought experiment — I can begin to explore what would follow from it. I can examine its consequences, test its internal coherence, and see whether unexpected insights emerge. Sometimes, speculative paths lead to surprising clarity, even if the initial assumption later proves untenable.
Many mainstream scientists would dismiss such exercises as a waste of time. They judge ideas by their empirical payoff. But some of the deepest insights begin with a question for which no data yet exists. They begin with a “what if?” — with a moment of intellectual openness toward an unexplored space of possibility. Those who argue only retrospectively can discover only what fits within the established frame. Truly new ideas require a willingness to step into the unknown, to hypothesize, to play.
I believe this exploratory, playful spirit is an essential part of science and philosophy. Not as a rejection of rigor, but as its necessary counterpart. We need both: the discipline of proof and the freedom of thought. Only then can we truly discover something new — even if we don’t yet know where it might lead.

Ultralight Dark Matter Detection with Superconducting Qubits
Tumblr media
Detecting Ultralight Dark Matter
Superconducting qubit networks detect lightweight dark matter better. Research improves network topology and measurement approaches to outperform standard detection methods while supporting quantum hardware. Bayesian inference, which resists local noise, extracts dark matter phase shifts.
The enigma of dark matter continues to test modern physics, prompting research into new detection methods. A recent study describes a quantum sensor network that employs quantum entanglement and optimised measurement techniques to detect ultralight dark matter fluxes. In “Optimised quantum sensor networks for ultralight dark matter detection,” Tohoku University researchers Adriel I. Santoso (Department of Mechanical and Aerospace Engineering) and Le Bin Ho (Frontier Research Institute for Interdisciplinary Sciences and Department of Applied Physics) present their findings. They found that interconnected superconducting qubits in diverse network topologies improve detection over standard quantum protocols even in noisy conditions.
Scientists are perfecting methods to detect dark matter, a non-luminous element predicted to make up over 85% of the cosmos, despite its resistance to direct detection. A recent study offers a network-based sensing architecture that uses superconducting qubits to boost ultralight dark matter flux sensitivity to overcome single-sensor disadvantages.
This approach relies on building networks of superconducting qubits with superposition and entanglement and connecting them with controlled-Z gates. These gates change qubit quantum states to enable correlated measurements. Researchers tested linear chains, rings, star configurations, and entirely linked graphs to find the best network structure for signal detection.
The study optimises quantum state preparation and measurement using variational metrology. Reducing the Cramer-Rao constraints, which limit quantum and classical parameter estimation accuracy, is necessary. By carefully altering these parameters, scientists can explore previously unreachable parameter space and identify setups that boost dark matter signal sensitivity.
Dark matter interactions should produce tiny quantum phase shifts in qubits. Bayesian inference, a statistical method for updating beliefs based on evidence, extracts phase shifts from measurement results for reliable signal recovery and analysis. Well-planned network topologies outperform Greenberger-Horne-Zeilinger (GHZ) protocols, a quantum sensing benchmark.
Practicality is a major benefit of this strategy. Because optimised networks maintain modest circuit depths, quantum computations require fewer sequential operations. Current noisy intermediate-scale quantum (NISQ) hardware limits quantum coherence, making this crucial. The work also exhibits robustness to local dephasing noise, a common mistake in quantum systems caused by environmental interactions, ensuring reliable performance under actual conditions.
This study emphasises network structure's role in dark matter detection. Researchers employ entanglement and network topology optimisation to build scalable approaches for enhancing sensitivity and expanding dark matter search. Future study will examine complex network topologies and develop advanced data processing methods to improve sensitivity and precision. Integration with current astrophysical observations and direct detection research could lead to a complex dark matter mystery solution.
Squeezer
A technology developed by UNSW researchers may help locate dark matter. Using “squeezing,” Associate Professor Jarryd Pla's group created an amplifier that can precisely detect weak microwave signals. One signal property is measured ultra-precisely while another is uncertainly reduced. Axions, hypothetical dark matter particles, may be found faster with the device. Future quantum computers and spectroscopy may benefit from the team's knowledge.
Quantum Engineers Create Dark Matter Research Amplifier
Sydney's University of New South Wales (UNSW) quantum engineers developed a new amplifier that may help researchers locate dark matter particles. This device accurately measures very faint microwave waves by "squeezing."
Squeezing decreases signal uncertainty for an ultra-precise measurement. Because Werner Heisenberg's uncertainty principle forbids simultaneous particle position and velocity measurements, this method is useful in quantum mechanics.
To set a world record, Associate Professor Jarryd Pla's team improved microwave signal monitoring, including cell phone signals. Noise, or signal fuzziness, limits signal measurement precision. However, the UNSW squeezer can exceed this quantum limit.
The Noise-Reducing Squeezer
The squeezer amplifies noise in one direction to substantially lower noise in another direction, or "squeeze." More accurate measurements arise from noise reduction. The gadget required substantial engineering and meticulous work to reduce loss causes. High-quality superconducting materials were employed to build the amplifier.
The team believes this new method could help find axions, which are theorised particles that have been hypothesised as the secret component of dark matter.
Searching for Axions: Dark Matter Key
Researchers need accurate measurements to identify dark matter, which makes about 27% of the universe. Nothing emits or absorbs light, making dark matter “invisible.” Astronomers believe it exists because its gravitational pull prevents galaxies from colliding.
Axions are one of many dark matter theories. These undiscovered particles are thought to be extremely light and tiny, allowing them to interact with other matter virtually softly. Axions should emit faint microwave signals under strong magnetic fields, according to one theory.
Axion Detection Squeezer
UNSW's squeezing work speeds up axion detection measurements by six times, improving the likelihood of finding an elusive axion. Axion detectors can measure faster and quieter with squeezers. The findings show those tests may be done faster, says A/Prof. Pla.
Wide Range of Squeezer Uses
The team's novel amplification approach may have uses beyond dark matter search. The squeezer works in stronger magnetic fields and at higher temperatures than prior models. The structure of novel materials and biological systems like proteins can be studied using spectroscopy. You can measure samples more accurately or explore smaller volumes with squeezed noise.
Additionally, compressed noise may be used in quantum computers. One type of quantum computer can be built utilising squeezed vacuum noise. Dr. Anders Kringhøj, part of the UNSW quantum technologies team, says our progress is comparable to what would be needed to build such a system.

Speaker recognition refers to the process used to recognize a speaker from a spoken phrase (Furui, n.d. 1). It is a useful biometric tool with wide applications e.g. in audio or video document retrieval. Speaker recognition is dominated by two procedures namely segmentation and classification. Research and development have been ongoing to design new algorithms or to improve on old ones that are used for doing segmentation and classification. Statistical concepts dominate the field of speaker recognition and they are used for developing models. Machines that are used for speaker recognition purposes are referred to as automatic speech recognition (ASR) machines. ASR machines are either used to identify a person or to authenticate the person’s claimed identity (Softwarepractice, n.d., p.1). The following is a discussion of various improvements that have been suggested in the field of speaker recognition. Two processes that are of importance in doing speaker recognition are audio classification and segmentation. These two processes are carried out using computer algorithms. In developing an ideal procedure for the process of audio classification, it is important to consider the effect of background noise. Because of this factor, an auditory model has been put forward by Chu and Champagne that exhibits excellent performance even in a noisy background. To achieve such robustness in a noisy background the model inherently has a self-normalization mechanism. The simpler form of the auditory model is expressed as a three-stage processing progression through which an audio signal goes through an alteration to turn into an auditory spectrum, which is models inside neural illustration. Shortcomings associated with the use of this model are that it involves nonlinear processing and high computational requirements. These shortcomings necessitate the need for a simpler version of the model. A proposal put forward by the Chu and Champagne (2006)suggests modifications on the model that create a simpler version of it that is linear except in getting the square-root value of energy (p. 775). The modification is done on four of the original processing steps namely pre-emphasis, nonlinear compression, half-wave rectification, and temporal integration. To reduce its computational complexity the Parseval theorem is applied which enables the simplified model to be implemented in the frequency domain. The resultant effect of these modifications is a self-normalized FFT-based model that has been applied and tested in speech/music/noise classification. The test is done with the use of a support vector machine (SVM) as the classifier. The result of this test indicates that a comparison of the original and proposed auditory spectrum to a conventional FFT-based spectrum suggests a more robust performance in noisy environments (p.775). Additionally, the results suggest that by reducing the computational complexity, the performance of the conventional FFT-based spectrum is almost the same as that of the original auditory spectrum (p.775). One of the important processes in speaker recognition and in radio recordings is speech/music discrimination.. The discrimination is done using speech/music discriminators. The discriminator proposed by Giannakopoulos et al. involves a segmentation algorithm (V-809). Audio signals exhibit changes in the distribution of energy (RMS) and it is on this property that the audio segmentation algorithm is founded on. The discriminator proposed by Giannakopoulos et al involves the use of Bayesian networks (V-809). A strategic move, which is ideal in the classification stage of radio recordings, is the adoption of Bayesian networks. Each of the classifiers is trained on a single and distinct feature, thus, at any given classification nine features are involved in the process. By operating in distinct feature spaces, the independence between the classifiers is increased. This quality is desirable, as the results of the classifiers have to be combined by the Bayesian network in place. The nine commonly targeted features, which are extracted from an audio segment, are Spectral Centroid, Spectral Flux, Spectral Rolloff, Zero Crossing Rate, Frame Energy and 4 Mel-frequency cepstral coefficients. The new feature selection scheme that is integrated on the discriminator is based on the Bayesian networks (Giannakopoulos et al, V-809). Three Bayesian network architectures are considered and the performance of each is determined. The BNC Bayesian network has been determined experimentally, and found to be the best of the three owing to reduced error rate (Giannakopoulos et al, V-812). This proposed discriminator has worked on real internet broadcasts of the British Broadcasting Corporation (BBC) radio stations (Giannakopoulos et al, V-809). An important issue that arises in speaker recognition is the ability to determine the number of speakers involved in an audio session. Swamy et al. (2007) have put forward a mechanism that is able to determine the number of speakers (481). In this mechanism, the value is determined from multispeaker speech signals. According to Swamy et al., one pair of microphones that are spatially separated is sufficient to capture the speech signals (481). A feature of this mechanism is the time delay experienced in the arrival of these speech signals. This delay is because of the spatial separation of the microphones. The mechanism has its basis on the fact that different speakers will exhibit different time delay lengths. Thus, it is this variation in the length of the time delay, which is exploited in order to determine the number of speakers. In order to estimate the length of time delay, a cross-correlation procedure is undertaken. The procedure cross-correlates to the Hilbert envelopes, which correspond to linear prediction residuals of the speech signals. According to Zhang and Zhou (2004), audio segmentation is one of the most important processes in multimedia applications (IV-349). One of the typical problems in audio segmentation is accuracy. It is also desirable that the segmentation procedure can be done online. Algorithms that have attempted to deal with these two issues have one thing in common. The algorithms are designed to handle the classification of features at small-scale levels. These algorithms additionally result in high false alarm rates. Results obtained from experiments reveal that the classification of large-scale audio is easily compared to small-scale audio. It is this fact that has necessitated an extensive framework that increases robustness in audio segmentation. The proposed segmentation methodology can be described in two steps. In the first step, the segmentation is described as rough and the classification is large-scale.   This step is taken as a measure of ensuring that there is integrality with respect to the content segments. By accomplishing this step you ensure that audio that is consecutive and that is from one source is not partitioned into different pieces thus homogeneity is preserved. In the second step, the segmentation is termed subtle and is undertaken to find segment points. These segment points correspond to boundary regions, which are the output of the first step. Results obtained from experiments also reveal that it is possible to achieve a desirable balance between the false alarm and low missing rate. The balance is desirable only when these two rates are kept at low levels (Zhang & Zhou, IV-349). According to Dutta and Haubold (2009), the human voice conveys speech and is useful in providing gender, nativity, ethnicity and other demographics about a speaker (422). Additionally, it also possesses other non-linguistic features that are unique to a given speaker (422). These facts about the human voice are helpful in doing audio/video retrieval. In order to do a classification of speaker characteristics, an evaluation is done on features that are categorized either as low-, mid- or high – level. MFCCs, LPCs, and six spectral features comprise the low-level features that are signal-based. Mid-level features are statistical in nature and used to model the low-level features. High-level features are semantic in nature and are found on specific phonemes that are selected. This describes the methodology that has been put forward by Dutta and Haubold (Dutta &Haubold, 2009, p.422). The data set that is used in assessing the performance of the methodology is made up of about 76.4 hours of annotated audio. In addition, 2786 segments that are unique to speakers are used for classification purposes. The results from the experiment reveal that the methodology put forward by Dutta and Haubold yields accuracy rates as high as 98.6% (Dutta & Haubold, 422). However, this accuracy rate is only achievable under certain conditions. The first condition is that test data is for male or female classification. The second condition to be observed is that in the experiment only mid-level features are used. The third condition is that the support vector machine used should posses a linear kernel. The results also reveal that mid- and high- level features are the most effective in identifying speaker characteristics. To automate the processes of speech recognition and spoken document retrieval the impact of unsupervised audio classification and segmentation has to be considered thoroughly. Huang and Hansen (2006) propose a new algorithm for audio classification to be used in automatic speech recognition (ASR) procedures (907). GMM networks that are weighted form the core feature of this new algorithm. Captured within this algorithm are the VSF and VZCR. VSF and VZCR are, additionally, extended-time features that are crucial to the performance of the algorithm. VSF and VZCR perform a pre-classification of the audio and additionally attach weights to the output probabilities of the GMM networks. After these two processes, the WGN networks implement the classification procedure. For the segmentation process in automatic speech recognition (ASR) procedures, Huang and Hansen (2006) propose a compound segmentation algorithm that captures 19 features (p.907). The figure below presents the features proposed Figure 1. Proposed features. Number required Feature name 1 2-mean distance metric 1 perceptual minimum variance distortionless response ( PMVDR) 1 Smoothed zero-crossing rate (SZCR) 1 False alarm compensation procedure 14 Filterbank log energy coefficients (FBLC) The 14 FBLCs proposed are implemented in 14 noisy environments where they are used to determine the best overall robust features with respect to these conditions. Turns lasting up to 5 seconds can be enhanced for short segment. In such case 2-mean distance metric is can be installed. The false alarm compensation procedure has been determined to boost efficiency of the rate at a cost effective manner. A comparison involving Huang and Hansen’s proposed classification algorithm against a GMM network baseline algorithm for classification reveals a 50% improvement in performance. Similarly, a comparison involving Huang and Hansen’s proposed compound segmentation algorithm against a baseline Mel-frequency cepstral coefficients (MFCC) and traditional Bayesian information criterion (BIC) algorithm reveals a 23%-10% improvement in all aspects (Huang and Hansen, 2006, p. 907). The data set used for the comparison procedure comprises of broadcast news evaluation data gotten from DARPA. DARPA is short for Defense Advanced Research Projects Agency. According to Huang and Hansen (2006), these two proposed algorithms achieve satisfactory results in the National Gallery of the Spoken Word (NGSW) corp, which is a more diverse, and challenging test. The basis of speaker recognition technology in use today is predominated by the process of statistical modeling. The statistical model formed is of short-time features that are extracted from acoustic speech signals. Two factors come into play when determining the recognition performance; these are the discrimination power associated with the acoustic features and the effectiveness of the statistical modeling techniques. The work of Chan et al is an analysis of the speaker discrimination power as it relates to two vocal features (1884). These two vocal features are either vocal source or conventional vocal tract related. The analysis draws a comparison between these two features. The features that are related to the vocal source are called wavelet octave coefficients of residues (WOCOR) and these have to be extracted from the audio signal. In order to perform the extraction process linear predictive (LP) residual signals have to be induced. This is because the linear predictive (LP) residual signals are compatible with the pitch-synchronous wavelet transform that perform the actual extraction. To determine between WOCOR and conventional MFCC features, which are least discriminative when a limit is placed on the amount of audio data consideration, is made to the degree of sensitivity to speech. Being less sensitive to spoken content and more discriminative in the face of a limited amount of training data are the two advantages that make WOCOR suitable for use in the task of speaker segmentation in telephone conversations (Chan et al, 1884). Such a task is characterized by building statistical speaker models upon short segments of speech. Additionally, experiments undertaken also reveal a significant reduction of errors associated with the segmentation process when WOCORs are used (Chan et al, 1884). Automatic speaker recognition (ASR) is the process through which a person is recognized from a spoken phrase by the aid of an ASR machine (Campbell, 1997, p.1437). Automatic speaker recognition (ASR) systems are designed and developed to operate in two modes depending on the nature of the problem to be solved. In one of the modes, they are used for identification purposes and in the other; they are used for verification or authentication purposes. In the first mode, the process is known as automatic speaker verification (ASV) while in the second the process is known as automatic speaker identification (ASI). In ASV procedures, the person’s claimed identity is authenticated by the ASR machine using the person’s voice. In ASI procedures unlike the ASV ones there is no claimed identity thus it is up to the ASR machine to determine the identity of the individual and the group to which the person belongs. Known sources of error in ASV procedures are shown in the table below Tab.2 Sources of verification errors. Misspoken or misread prompted phases Stress, duress and other extreme emotional states Multipath, noise and any other poor or inconsistent room acoustics The use of different microphones for verification and enrolment or any other cause of Chanel mismatch Sicknesses especially those that alter the vocal tract Aging Time varying microphone placement According to Campbell, a new automatic speaker recognition system is available and the recognizer is known to perform with 98.9% correct identification levels (p.1437 Signal acquisition is a basic building block for the recognizer. Feature extraction and selection is the second basic unit of the recognizer. Pattern matching is the third basic unit of the recognizer. A decision criterion is the fourth basic unit of the proposed recognizer. According to Ben-Harush et al. (2009), speaker diarization systems are used in assigning temporal speech segments in a conversation to the appropriate speaker (p.1). The system also assigns non-speech segments to non-speech. The problem that speaker diarization systems attempt to solve is captured in the query “who spoke when?” An inherent shortcoming in most of the diarization systems in use today is that they are unable to handle speech that is overlapped or co-channeled. To this end, algorithms have been developed in recent times seeking to address this challenge. However, most of these require unique conditions in order to perform and necessitate the need for high computational complexity. They also require that an audio data analysis with respect to time and frequency domain be undertaken. Ben-Harush et al. (2009) have proposed a methodology that uses frame based entropy analysis, Gaussian Mixture Modeling (GMM) and well known classification algorithms to counter this challenge (p.1). To perform overlapped speech detection, the methodology suggests an algorithm that is centered on a single feature. This single feature is an entropy analysis of the audio data in the time domain. To identify speech segments that are overlapped the methodology uses the combined force of Gaussian Mixture Modeling (GMM) and well-known classification algorithms. The methodology proposed by Ben-Harush et al is known to detect 60.0 % of frames containing overlapped speech (p.1). This value is achieved when the segmentation is at baseline level (p.1). It is capable of achieving this value while it maintains the rate of false alarm at 5 (p.1). Overlapped speech (OS) contributes to degrading the performance of automatic speaker recognition systems. Conversations over the telephone or during a meeting possess high quantities of overlapped speech. Du et al (200&) brings out audio segmentation as a problem in TV series, movies and other forms of practical media (I-205). Practical media exhibits audio segments of varying lengths but of these, short ones are easily noticeable due to their number. Through audio segmentation, an audio stream is broken down into parts that are homogenous with respect to speaker identity, acoustic class and environmental conditions..Du et al. (2007) has formulated an approach to unsupervised audio segmentation to be used in all forms of practical media. Included in this approach is a segmentation-stage at which potential acoustic changes are detected. Also included is a refinement-stage during which the detected acoustic changes are refined by a tri-model Bayesian Information Criterion (BIC). Results from experiments suggest that the approach possesses a high capability for detecting short segments (Du et al, I-205). Additionally, the results suggest that the tri-model BIC is effective in improving the overall segmentation performance (Du et al, I-205). According to Hosseinzadeh and Krishnan (2007), the concept of speaker recognition processes seven spectral features. The first of these spectral features is the Spectral centroid (SC). Hosseinzadeh and Krishnan (2007, p.205), state “the second spectral feature is Spectral bandwidth (SBW), the third is spectral band energy (SBE), the fourth is spectral crest factor (SCF), the fifth is Spectral flatness measure (SFM), the sixth is Shannon entropy (SE) and the seventh is Renyi entropy (RE)”. The seven features are used for quantification, which is important in speaker recognition since it is the case where vocal source information and the vocal tract function complements each other. The vocal truct function is determined specifically using two coefficients these are the MFCC and LPCC. MFCC stands for Mel frequency coefficients and LPCC stands for linear prediction cepstral coefficients. The quantification is quite significant in speaker detection as it is the container where verbal supply information and the verbal tract function are meant to balance. Very important in an experiment done to analyze the performance of these features is the use of a speaker identification system (SIS). ). A cohort Gaussian mixture model which is additionally text-independent is forms the ideal choice of a speaker identification method that is used in the experiment. The results from such an experiment reveal that these features achieve an identification accuracy of 99.33%. This accuracy level is achieved only when these features are combined with those that are MFCC based and additionally when undistorted speech is used. Read the full article

Advanced Statistical Methods for Data Analysts: Going Beyond the Basics
Introduction
Advanced statistical methods are a crucial toolset for data analysts looking to gain deeper insights from their data. While basic statistical techniques like mean, median, and standard deviation are essential for understanding data, advanced methods allow analysts to uncover more complex patterns and relationships.
Advanced Statistical Methods for Data Analysts
Data analysis has statistical theorems as its foundation. These theorems are stretched beyond basic applications to advanced levels by data analysts and scientists to fully exploit the possibilities of data science technologies. For instance, an entry-level course in any Data Analytics Institute in Delhi would cover the basic theorems of statistics as applied in data analysis while an advanced-level or professional course will teach learners some advanced theorems of statistics and how those theorems can be applied in data science. Some of the statistical theorems that extent beyond the basic ones are:
Regression Analysis: One key advanced method is regression analysis, which helps analysts understand the relationship between variables. For instance, linear regression can be utilised to estimate the value of a response variable using various input variables. This can be particularly useful in areas like demand forecasting and risk management.
Cluster Analysis: Another important method is cluster analysis, in which similar data points are grouped together. This can be handy for identifying patterns in data that may not be readily visible, such as customer segmentation in marketing.
Time Series Analysis: This is another advanced method that is used to analyse data points collected over time. This can be handy for forecasting future trends based on past data, such as predicting sales for the next quarter based on sales data from previous quarters.
Bayesian Inference: Unlike traditional frequentist statistics, Bayesian inference allows for the incorporation of previous knowledge or beliefs about a parameter of interest to make probabilistic inferences. This approach is particularly functional when dealing with small sample sizes or when prior information is available.
Survival Analysis: Survival analysis is used to analyse time-to-event data, such as the time until a patient experiences a particular condition or the time until a mechanical component fails. Techniques like Kaplan-Meier estimation and Cox proportional hazards regression are commonly used in survival analysis.
Spatial Statistics: Spatial statistics deals with data that have a spatial component, such as geographic locations. Techniques like spatial autocorrelation, spatial interpolation, and point pattern analysis are used to analyse spatial relationships and patterns.
Machine Learning: Machine learning involves advanced statistical techniques—such as ensemble methods, dimensionality reduction, and deep learning, that go beyond the fundamental theorems of statistics. These are typically covered in an advanced Data Analytics Course.
Causal Inference: Causal inference is used to identify causal relationships between variables dependent on observational data. Techniques like propensity score matching, instrumental variables, and structural equation modelling are used to estimate causal effects.
Text Mining and Natural Language Processing (NLP): Techniques in text mining and natural language processing are employed to analyse unstructured text data. NLP techniques simplify complex data analytics methods, rendering them comprehensible for non-technical persons. Professional data analysts need to collaborate with business strategists and decision makers who might not be technical experts. Many organisations in commercialised cities where data analytics is used for achieving business objectives require their workforce to gain expertise in NLP. Thus, a professional course from a Data Analytics Institute in Delhi would have many enrolments from both technical and non-technical professionals aspiring to acquire expertise in NLP.  
Multilevel Modelling: Multilevel modelling, also known as hierarchical or mixed-effects modelling, helps with analysing nested structured data. This approach allows for the estimation of both within-group and between-group effects.
Summary
Overall, advanced statistical methods are essential for data analysts looking to extract meaningful insights from their data. By going beyond the basics, analysts can uncover hidden patterns and relationships that can lead to more informed decision-making. Statistical theorems are mandatory topics in any Data Analytics Course; only that the more advanced the course level, the more advanced the statistical theorems taught in the course.

The Paradox of Probabilistic and Deterministic Worlds in AI and Quantum Computing
In the fascinating realms of artificial intelligence (AI) and quantum computing, a curious paradox emerges when we examine the interplay between algorithms and hardware. AI algorithms are inherently probabilistic, while the hardware they run on is deterministic. Conversely, quantum algorithms are deterministic, yet the hardware they rely on is probabilistic. This duality highlights the unique challenges and opportunities in these cutting-edge fields.
AI: Probabilistic Algorithms on Deterministic Hardware
AI algorithms, particularly those in machine learning, often rely on probabilistic methods to make predictions or decisions. Techniques like Bayesian inference, stochastic gradient descent, and Monte Carlo simulations are rooted in probability theory. These algorithms embrace uncertainty, using statistical models to approximate solutions where exact answers are computationally infeasible.
However, the hardware that executes these algorithms—traditional CPUs and GPUs—is deterministic. These processors follow precise instructions and produce predictable outcomes for given inputs. The deterministic nature of classical hardware ensures reliability and reproducibility, which are crucial for debugging and scaling AI systems. Yet, this mismatch between probabilistic algorithms and deterministic hardware can lead to inefficiencies, as the hardware isn't inherently designed to handle uncertainty.
Quantum Computing: Deterministic Algorithms on Probabilistic Hardware
In contrast, quantum computing presents an inverse scenario. Quantum algorithms, such as Shor's algorithm for factoring integers or Grover's algorithm for search problems, are deterministic. They are designed to produce specific, correct outcomes when executed correctly. However, the quantum hardware that runs these algorithms is inherently probabilistic.
Quantum bits (qubits) exist in superpositions of states, and their measurements yield probabilistic results. This probabilistic nature arises from the fundamental principles of quantum mechanics, such as superposition and entanglement. While quantum algorithms are designed to harness these phenomena to solve problems more efficiently than classical algorithms, the hardware's probabilistic behavior introduces challenges in error correction and result verification.
Bridging the Gap
The dichotomy between probabilistic algorithms and deterministic hardware in AI, and deterministic algorithms and probabilistic hardware in quantum computing, underscores the need for innovative approaches to bridge these gaps. In AI, researchers are exploring neuromorphic and probabilistic computing architectures that better align with the probabilistic nature of AI algorithms. These hardware innovations aim to improve efficiency and performance by embracing uncertainty at the hardware level.
In quantum computing, advancements in error correction and fault-tolerant designs are crucial to mitigate the probabilistic nature of quantum hardware. Techniques like quantum error correction codes and surface codes are being developed to ensure reliable and deterministic outcomes from quantum algorithms.
Conclusion
The interplay between probabilistic and deterministic elements in AI and quantum computing reveals the intricate balance required to harness the full potential of these technologies. As we continue to push the boundaries of computation, understanding and addressing these paradoxes will be key to unlocking new possibilities and driving innovation in both fields. Whether it's designing hardware that aligns with the probabilistic nature of AI or developing methods to tame the probabilistic behavior of quantum hardware, the journey promises to be as exciting as the destination.
