Typical … WebAug 29, 2024 · One can use any kind of estimator such as sklearn.svm SVC, sklearn.linear_model LogisticRegression or sklearn.ensemble RandomForestClassifier. The outcome of grid search is the optimal combination of one or more hyper parameters that gives the most optimal model complying to bias-variance tradeoff. WebThe limitations of grid search are pretty straightforward: Grid search does not scale well. There is a huge number of combinations we end up testing for just a few parameters. For example, if we have 4 parameters, and we want to test 10 values for each parameter, there are : \(10 \times 10 \times 10 \times 10 = 10'000\) combinations possible. green tea and black tea
