WebIn this, I want to tune the parameter weights. If I use GridSearchCV, it is taking a lot of time. Since it needs to fit the model for each iteration. Which is not required, I guess. Better would be use something like prefit used in SelectModelFrom function from sklearn.model_selection. Is there any other option or I am misinterpreting something ...

WebThe experiment was conducted using Support Vector Machine (SVM), K-Nearest Neighbor (K-NN), and Logistic Regression (LR) classifiers. To improve models' accuracy, SMOTETomek was employed along with GridsearchCV to tune hyperparameters. The Re-cursive Feature Elimination method was also utilized to find the best feature subset.

First, the AdaBoost ensemble is fit on all available data, then the predict () function can be called to make predictions on new data. The example below demonstrates this on our regression dataset. 1. 2. henley and cowes
