Gridsearchcv get accuracy
WebAn important task in ML is model selection, or using data to find the best model or parameters for a given task. This is also called tuning . Tuning may be done for individual Estimator s such as LogisticRegression, or for entire Pipeline s which include multiple algorithms, featurization, and other steps. Users can tune an entire Pipeline at ... WebSuppose I am using an XGBoost model with default params which gives me suppose 80% accuracy.
