WebNov 24, 2024 · How do I speed up GridSearchCV? You can get an instant 2-3x speedup by switching to 5- or 3-fold CV (i.e., cv=3 in the GridSearchCV call) without any meaningful difference in performance estimation. Try fewer parameter options at each round. With 9×9 combinations, you’re trying 81 different combinations on each run. crystal priyaWebGridSearchCV inherits the methods from the classifier, so yes, you can use the .score, .predict, etc.. methods directly through the GridSearchCV interface.
