WebMay 24, 2024 · 98 4. There's a possibility that there is a mistake in your code other than the above. One possibility it that logistic regression is overfitting to the training set when doing GridSearchCV. Note that reported training accuracy in GridSearchCV might be the CV accruacy of the training set. Hence it reports a lower training accuracy. WebRecently, scikit-learn added the experimental hyperparameter search estimators halving grid search (HalvingGridSearchCV) and halving random search (HalvingRandomSearch). The image below is from the documentation. These techniques can be used to search the parameter space using successive halving. All hyperparameter candidates are evaluated …
