Jax Syntax and Examples
Jax syntax revolves around functional programming principles, making heavy use of transformations and higher-order functions. Key components include jit for just-in-time compilation, grad for automatic differentiation, and vmap for vectorization. Here’s a simple example showcasing Jax syntax:
| import jax.numpy as jnp from jax import jit, grad # Define a simple function def square(x): return x ** 2 # JIT-compile the function for faster execution square_jit = jit(square) # Compute gradients using automatic differentiation grad_square = grad(square) # Vectorize function for array inputs square_vectorized = jit(vmap(square)) # Example usage x = jnp.array(3.0) print(“Square of”, x, “:”, square_jit(x)) print(“Gradient of square at”, x, “:”, grad_square(x)) # Example with array inputs x_array = jnp.array([1.0, 2.0, 3.0]) print(“Square of array:”, square_vectorized(x_array) |
In this example, jit optimizes the function for faster execution, grad computes the gradient, and vmap vectorizes the function for array inputs. This demonstrates the core syntax and usage of Jax functionalities.
