So... I think I've just finished writing a 7.7 or 7.8K words long chapter in 2-3 days.

What the fuck possessed me? Did I finally manage to build up a working writing routine for me?

Did suffering the fanfic writer curse in advance really payout and work?

Anyways, am currently editing my current stp truth lies AU chapter "The drowned Cage" there. Will archive locked post it then. Maybe put up a publically encrypted/enciphered version of the fic once I got Maddening Shackles fully written down and posted.

But breakfast first! Food.

Hanging out around other people interested in AI has only made me more and more conservative on the subject as I realize how few people have any interest in producing artworks ethically while using statistical generation as a tool.

Like 85% of the use cases I see are just people making niche memes for themselves. They wouldn't have hired an artist for it anyway.

But then the other 14% is like. One guy personally eliminating all concept art positions from multiple game studios in a week. Putting dozens of lifetime professional artists out of work in an instant for a dramatically inferior product made of stolen works. That kind of shit.

And I don't think the 1% of people making public domain based models on 120 year old pulp media magazine ad art are keeping up. Like. I just don't think we are.

Getting It Right vs Getting It Done

With all the hype around machine learning, I occasionally get asked if it could be used to make predictions for particle colliders, like the LHC. Physicists do use machine learning these days, to be clear. There are tricks and heuristics, ways to quickly classify different particle collisions and speed up computation. But if you’re imagining something that replaces particle physics calculations…

I think one of the most interesting parts of my (thus short) career as a mechanical engineer is that we are taught all sorts of first-principles physics and complex science. And then it turns out that geometric dimensioning and tolerancing, one of the most important and fundamental areas of knowledge for mechanical design and manufacturing and assembly to the point that anybody even incidentally involved in it industrially is aware of it and why it is used, was not only not taught to us during our college education but was in fact not mentioned once at any point even during our drafting courses.

The Mathematical Foundations of Machine Learning

In the world of artificial intelligence, machine learning is a crucial component that enables computers to learn from data and improve their performance over time. However, the math behind machine learning is often shrouded in mystery, even for those who work with it every day. Anil Ananthaswami, author of the book "Why Machines Learn," sheds light on the elegant mathematics that underlies modern AI, and his journey is a fascinating one.

Ananthaswami's interest in machine learning began when he started writing about it as a science journalist. His software engineering background sparked a desire to understand the technology from the ground up, leading him to teach himself coding and build simple machine learning systems. This exploration eventually led him to appreciate the mathematical principles that underlie modern AI. As Ananthaswami notes, "I was amazed by the beauty and elegance of the math behind machine learning."

Ananthaswami highlights the elegance of machine learning mathematics, which goes beyond the commonly known subfields of calculus, linear algebra, probability, and statistics. He points to specific theorems and proofs, such as the 1959 proof related to artificial neural networks, as examples of the beauty and elegance of machine learning mathematics. For instance, the concept of gradient descent, a fundamental algorithm used in machine learning, is a powerful example of how math can be used to optimize model parameters.

Ananthaswami emphasizes the need for a broader understanding of machine learning among non-experts, including science communicators, journalists, policymakers, and users of the technology. He believes that only when we understand the math behind machine learning can we critically evaluate its capabilities and limitations. This is crucial in today's world, where AI is increasingly being used in various applications, from healthcare to finance.

A deeper understanding of machine learning mathematics has significant implications for society. It can help us to evaluate AI systems more effectively, develop more transparent and explainable AI systems, and address AI bias and ensure fairness in decision-making. As Ananthaswami notes, "The math behind machine learning is not just a tool, but a way of thinking that can help us create more intelligent and more human-like machines."

Matrices are used to organize and process complex data, such as images, text, and user interactions, making them a cornerstone in applications like Deep Learning (e.g., neural networks), Computer Vision (e.g., image recognition), Natural Language Processing (e.g., language translation), and Recommendation Systems (e.g., personalized suggestions). To leverage matrices effectively, AI relies on key mathematical concepts like Matrix Factorization (for dimension reduction), Eigendecomposition (for stability analysis), Orthogonality (for efficient transformations), and Sparse Matrices (for optimized computation).

Transformers are a type of neural network architecture introduced in 2017 by Vaswani et al. in the paper “Attention Is All You Need”. They revolutionized the field of NLP by outperforming traditional recurrent neural network (RNN) and convolutional neural network (CNN) architectures in sequence-to-sequence tasks. The primary innovation of transformers is the self-attention mechanism, which allows the model to weigh the importance of different words in the input data irrespective of their positions in the sentence. This is particularly useful for capturing long-range dependencies in text, which was a challenge for RNNs due to vanishing gradients. Transformers have become the standard for machine translation tasks, offering state-of-the-art results in translating between languages. They are used for both abstractive and extractive summarization, generating concise summaries of long documents. Transformers help in understanding the context of questions and identifying relevant answers from a given text. By analyzing the context and nuances of language, transformers can accurately determine the sentiment behind text. While initially designed for sequential data, variants of transformers (e.g., Vision Transformers, ViT) have been successfully applied to image recognition tasks, treating images as sequences of patches. Transformers are used to improve the accuracy of speech-to-text systems by better modeling the sequential nature of audio data. The self-attention mechanism can be beneficial for understanding patterns in time series data, leading to more accurate forecasts.

Attention is all you need (Umar Hamil, May 2023)

Geometric deep learning is a subfield of deep learning that focuses on the study of geometric structures and their representation in data. This field has gained significant attention in recent years.

Michael Bronstein: Geometric Deep Learning (MLSS Kraków, December 2023)

Traditional Geometric Deep Learning, while powerful, often relies on the assumption of smooth geometric structures. However, real-world data frequently resides in non-manifold spaces where such assumptions are violated. Topology, with its focus on the preservation of proximity and connectivity, offers a more robust framework for analyzing these complex spaces. The inherent robustness of topological properties against noise further solidifies the rationale for integrating topology into deep learning paradigms.

Hyperparameter tuning in machine learning

The performance of a machine learning model in the dynamic world of artificial intelligence is crucial, we have various algorithms for finding a solution to a business problem. Some algorithms like linear regression , logistic regression have parameters whose values are fixed so we have to use those models without any modifications for training a model but there are some algorithms out there where the values of parameters are not fixed.

Here's a complete guide to Hyperparameter tuning in machine learning in Python!

The problem is that due to the way AI art is created it's difficult to impossible to tell if the algorithm is making completely new stuff by cutting things up and piecing them together or if they're just a very slightly changed picture that was used to train it. The sheer volume of training data is so large that no one will ever know all of it. I have seen that this issue does occur with AI that is supposed to create faces. The faces it supposedly created were just ripped from its training data and distorted very slightly.

hmm if that is indeed happening, there's definitely a problem. my gut reaction is to say that transparency would solve this issue, so that people who understand code could see Why some bots are doing that and fix it so that they cant (or tell other people "hey this bot is crap and super illegal"). i guess part of the issue there is; can we tell if AI is *conceptually* a problem, or are there *specific bots* that are poorly made that aren't doing what they're supposed to? i would hope that this is more an issue of like, specific bots being shit, because my understanding of machine learning shouldn't allow for that at all.
