In case you are struggling with how to pass the fit_params, which happened to me as well, this is how you should do that: fit_params = {'categorical_feature':indexes_of_categories} clf = GridSearchCV (model, param_grid, cv=n_folds) clf.fit (x_train, y_train, **fit_params) Share. Improve this answer. Follow. WebTune Parameters for the Leaf-wise (Best-first) Tree. LightGBM uses the leaf-wise tree growth algorithm, while many other popular tools use depth-wise tree growth. Compared with depth-wise growth, the leaf-wise algorithm can converge much faster. However, the leaf-wise growth may be over-fitting if not used with the appropriate parameters.
