Grid Search
Domain: MLOps
🎯 Motivation
Trying all combinations of hyperparameters systematically. Thorough but slow.
📋 Concrete Example
Grid: lr in {0.001, 0.01, 0.1} x batch in {32, 64, 128} = 9 combinations. Try all 9. Pick the best. Thorough but takes 9x training time.
🔗 Analogy
Trying every combination at a buffet - sample every dish x every sauce. Thorough but takes a long time. Grid search tries every hyperparameter combination.
