WebThe grid_search_params dictionary contains the control parameters that were used in each search. I performed 3-fold cross-validation on param_grid, which contains 4 CatBoost hyperparameters with 3 values each. The results were measured in root mean squared log error (RMSLE). In [4]: WebFirst let's see what kind of results we can generate without a grid search using only the base parameters. To get started we must first load in the dataset we will be working with. from sklearn import datasets iris = datasets.load_iris () Next in order to create the model we must have a set of independent variables X and a dependant variable y.
