import jax.numpy as jnp
from jax import grad, jit
# Define a function to minimize
def loss_function(x):
return jnp.sum((x - 3) ** 2)
# Compute the gradient of the loss function
gradient = grad(loss_function)
# Optimize the function using a simple gradient descent algorithm
@jit
def gradient_descent(x, learning_rate=0.1, steps=100):
for _ in range(steps):
grad_value = gradient(x)
x = x - learning_rate * grad_value
return x


# Initial value
x_init = jnp.array([5.0, 5.0])
# Optimize
optimized_x = gradient_descent(x_init)
print("Optimized x:", optimized_x)
