Grid Search Hyperparameters in Python
Perform exhaustive grid search over hyperparameter combinations using itertools.product and a scoring function.
import itertools
def grid_search(param_grid, score_fn):
"""Perform exhaustive grid search over hyperparameter combinations."""
keys = param_grid.keys()
names = list(keys)
values = [param_grid[name] for name in names]
results = []
for combination in itertools.product(*values):

A mock random search that samples hyperparameter combinations from a grid and ranks them by a dummy score, with a reproducible seed.
import random
# Mock random search over a small hyperparameter grid
param_grid = {
"learning_rate": [0.001, 0.01, 0.1],
"batch_size": [16, 32, 64],
"num_layers": [1, 2, 3]
}
def random_search(grid, n_iter=5, seed=42):
"""Perform random search over a hyperparameter grid."""
random.seed(seed)
