Core Concepts of JAX

Mastering the core concepts of JAX is crucial for anyone seeking to harness its full potential. This chapter will explore the fundamental principles that make JAX a powerful tool for numerical computing and machine learning. You'll begin with automatic differentiation, a vital feature that streamlines the calculation of derivatives, enabling efficient optimization in complex models.

We will also examine JAX's vectorization capabilities, allowing you to write code that operates on entire arrays, thereby optimizing performance and reducing the need for explicit loops. Another significant aspect we'll investigate is just-in-time compilation, which enhances execution speed by converting Python functions into optimized machine code. By the end of this chapter, you'll have a solid grasp of these key concepts, equipping you to implement them in practical scenarios.
