hi! i'm shy as hell usually but trying to branch out cuz i saw u reblog that post abt asks. do u have any recs on where to start for a beginner coder (who has virtually no free time)? i feel like the landscape is so vast and overwhelming.

Hiii!! Thanks for the ask!

I think the best thing I've learned throughout my coding journey is that you must first pick a field that interests you. Computer Science is a VAST world, once you pick a field, you must really commit to it. For example, maybe data science interests you. You look up the requirements to be a date scientist. I don't have in-depth knowledge on it, but I do know that you need good knowledge about python and some of its modules like numpy, matplotlib etc. So you start learning the basics, and then move on to the modules. The key is to find what you love, then find what you need in order to pursue it.

For a kickstart I'd recommend w3schools — it's a really good site that has so many tutorials on various languages.

I was also a person that had no free time at all to focus on my learning. But then I realised that you must make time if you want to work on something with dedication. So now I devote Sunday afternoons to learning and working on my projects, and I try to stick to it as much as possible, except for when I have uni exams or any submissions lol

Hope this helped!!

[studyblrspace]

hi! I love your blog. What programming languages would you recommend learning if you wanted to get into astrophysics? I already know c++, but I heard somewhere that python is better for data analysis?

I'm so sorry anon, I drafted an answer and then completely forgot to post it ���😭😭

the main programming languages I've seen are c++ and python. there's also julia (new), and fortran (🥴).

so its great you already know c++! personally I've used athena++ code for simulations if you wanted a simulation code to play with.

but python would be good to play around with if you're not familiar, its great for visualization / data analysis! I started by learning the syntax and about packages like numpy, matplotlib, and astropy. "Python for Astronomers" may be helpful if you need a resource for learning, it has a free textbook and some tutorials. part of my undergrad computational astrophysics course could was based on it! another fun package is yt, you can look up "python yt cookbook" or click here. this website also gives you sample data from a simulation run and lots of tutorials.

julia is not as widely used but its supposed to have the intuitiveness of python with the performance/speed of c++. it's a newer language, like 10 years old. I've heard that there is a (very slow) shift to this language in the astrophysics community instead of python. I don't have any resources because I haven't gotten around to learning it yet 😅

fortran is an older language, I can't say I'm familiar with it. I've only encountered it in a skeleton simulation code a postdoc was developing (and I was testing the code) so I just know basic syntax. you'd probably be fine not learning it, unless you want to develop your own simulation code soon

I'm only a couple years into (theoretical) astrophysics research so if anyone else has input, please let me know!!

Understanding Outliers in Machine Learning and Data Science

In machine learning and data science, an outlier is like a misfit in a dataset. It's a data point that stands out significantly from the rest of the data. Sometimes, these outliers are errors, while other times, they reveal something truly interesting about the data. Either way, handling outliers is a crucial step in the data preprocessing stage. If left unchecked, they can skew your analysis and even mess up your machine learning models.

In this article, we will dive into:

1. What outliers are and why they matter.

2. How to detect and remove outliers using the Interquartile Range (IQR) method.

3. Using the Z-score method for outlier detection and removal.

4. How the Percentile Method and Winsorization techniques can help handle outliers.

This guide will explain each method in simple terms with Python code examples so that even beginners can follow along.

1. What Are Outliers?

An outlier is a data point that lies far outside the range of most other values in your dataset. For example, in a list of incomes, most people might earn between $30,000 and $70,000, but someone earning $5,000,000 would be an outlier.

Why Are Outliers Important?

Outliers can be problematic or insightful:

Problematic Outliers: Errors in data entry, sensor faults, or sampling issues.

Insightful Outliers: They might indicate fraud, unusual trends, or new patterns.

Types of Outliers

1. Univariate Outliers: These are extreme values in a single variable.

Example: A temperature of 300°F in a dataset about room temperatures.

2. Multivariate Outliers: These involve unusual combinations of values in multiple variables.

Example: A person with an unusually high income but a very low age.

3. Contextual Outliers: These depend on the context.

Example: A high temperature in winter might be an outlier, but not in summer.

2. Outlier Detection and Removal Using the IQR Method

The Interquartile Range (IQR) method is one of the simplest ways to detect outliers. It works by identifying the middle 50% of your data and marking anything that falls far outside this range as an outlier.

Steps:

1. Calculate the 25th percentile (Q1) and 75th percentile (Q3) of your data.

2. Compute the IQR:

{IQR} = Q3 - Q1

Q1 - 1.5 \times \text{IQR}

Q3 + 1.5 \times \text{IQR} ] 4. Anything below the lower bound or above the upper bound is an outlier.

Python Example:

import pandas as pd

# Sample dataset

data = {'Values': [12, 14, 18, 22, 25, 28, 32, 95, 100]}

df = pd.DataFrame(data)

# Calculate Q1, Q3, and IQR

Q1 = df['Values'].quantile(0.25)

Q3 = df['Values'].quantile(0.75)

IQR = Q3 - Q1

# Define the bounds

lower_bound = Q1 - 1.5 * IQR

upper_bound = Q3 + 1.5 * IQR

# Identify and remove outliers

outliers = df[(df['Values'] < lower_bound) | (df['Values'] > upper_bound)]

print("Outliers:\n", outliers)

filtered_data = df[(df['Values'] >= lower_bound) & (df['Values'] <= upper_bound)]

print("Filtered Data:\n", filtered_data)

Key Points:

The IQR method is great for univariate datasets.

It works well when the data isn’t skewed or heavily distributed.

3. Outlier Detection and Removal Using the Z-Score Method

The Z-score method measures how far a data point is from the mean, in terms of standard deviations. If a Z-score is greater than a certain threshold (commonly 3 or -3), it is considered an outlier.

Formula:

Z = \frac{(X - \mu)}{\sigma}

 is the data point,

 is the mean of the dataset,

 is the standard deviation.

Python Example:

import numpy as np

# Sample dataset

data = {'Values': [12, 14, 18, 22, 25, 28, 32, 95, 100]}

df = pd.DataFrame(data)

# Calculate mean and standard deviation

mean = df['Values'].mean()

std_dev = df['Values'].std()

# Compute Z-scores

df['Z-Score'] = (df['Values'] - mean) / std_dev

# Identify and remove outliers

threshold = 3

outliers = df[(df['Z-Score'] > threshold) | (df['Z-Score'] < -threshold)]

print("Outliers:\n", outliers)

filtered_data = df[(df['Z-Score'] <= threshold) & (df['Z-Score'] >= -threshold)]

print("Filtered Data:\n", filtered_data)

Key Points:

The Z-score method assumes the data follows a normal distribution.

It may not work well with skewed datasets.

4. Outlier Detection Using the Percentile Method and Winsorization

Percentile Method:

In the percentile method, we define a lower percentile (e.g., 1st percentile) and an upper percentile (e.g., 99th percentile). Any value outside this range is treated as an outlier.

Winsorization:

Winsorization is a technique where outliers are not removed but replaced with the nearest acceptable value.

Python Example:

from scipy.stats.mstats import winsorize

import numpy as np

Sample data

data = [12, 14, 18, 22, 25, 28, 32, 95, 100]

Calculate percentiles

lower_percentile = np.percentile(data, 1)

upper_percentile = np.percentile(data, 99)

Identify outliers

outliers = [x for x in data if x < lower_percentile or x > upper_percentile]

print("Outliers:", outliers)

# Apply Winsorization

winsorized_data = winsorize(data, limits=[0.01, 0.01])

print("Winsorized Data:", list(winsorized_data))

Key Points:

Percentile and Winsorization methods are useful for skewed data.

Winsorization is preferred when data integrity must be preserved.

Final Thoughts

Outliers can be tricky, but understanding how to detect and handle them is a key skill in machine learning and data science. Whether you use the IQR method, Z-score, or Wins

orization, always tailor your approach to the specific dataset you’re working with.

By mastering these techniques, you’ll be able to clean your data effectively and improve the accuracy of your models.
