This is the code repository for 15 Math Concepts Every Data Scientist Should Know, published by Packt.

Understand and learn how to apply the math behind data science algorithms

As machine learning algorithms become more powerful, data scientists need a clear grasp of their key components. This book explains the core math principles underpinning the most used algorithms, detailing their importance and practical applications.

This book covers the following exciting features:

• Master foundational concepts that underpin all data science applications
• Use advanced techniques to elevate your data science proficiency
• Apply data science concepts to solve real-world data science challenges
• Implement the NumPy, SciPy, and scikit-learn concepts in Python
• Build predictive machine learning models with mathematical concepts
• Gain expertise in Bayesian non-parametric methods for advanced probabilistic modeling
• Acquire mathematical skills tailored for time-series and network data types

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

map_estimate = minimize(neg_log_posterior,
                        x0,
                        method='BFGS',
                        options={'disp': True})
# Convert from logit(p) to p
p_optimal = np.exp(map_estimate['x'][0])/ (
    1.0 + np.exp(map_estimate['x'][0]))
print("MAP estimate of success probability = ", p_optimal)

Following is what you need for this book: This book is for data scientists, machine learning engineers, and data analysts who already use data science tools and libraries but want to learn more about the underlying math. Whether you’re looking to build upon the math you already know, or need insights into when and how to adopt tools and libraries to your data science problem, this book is for you. Organized into essential, general, and selected concepts, this book is for both practitioners just starting out on their data science journey and experienced data scientists.

With the following software and hardware list you can run all code files present in the book (Chapter 2-15).
