Cross-Validation is a resampling technique that can be used to evaluate … WebYep I figured it out. The answer is that by default GridSearchCV's last act is to expose the API of the estimator object you passed so that you can directly call things like .predict() or .score() on the GridSearchCV object itself. It does this by retraining the estimator against the best parameters it found during cross validation.
