Pseudo-Random Numbers and Probability Distributions in JAX

Generating random numbers in machine learning can lead to unpredictable bugs and non-reproducible experiments if not handled correctly. This course teaches you how to manage state and randomness effectively using JAX's unique functional approach to pseudo-random number generation (PRNG). You will transition from basic concepts to building reproducible, high-performance machine learning components. By reading through this comprehensive guide, you will gain a strong mental model of how JAX handles random states differently than traditional libraries, enabling you to write deterministic, parallelizable, and bug-free code. What you'll learn: - Understand the core principles of stateless PRNG and why JAX uses explicit keys - Split and manage random keys safely across parallel operations and loops - Generate samples from common probability distributions like Normal, Uniform, and Binomial - Apply random state techniques to implement batch normalization in neural networks - Structure reproducible machine learning pipelines using modern functional programming patterns The course begins with foundational definitions of pseudo-randomness and the mechanics of JAX keys, ensuring you have a solid conceptual starting point. From there, you will explore practical statistical distributions and walk through the implementation of dynamic network layers like batch normalization. This course is designed for beginners to JAX, data scientists, and machine learning enthusiasts who want to master functional randomness without needing advanced mathematics.
