OptGBM：Optuna + LightGBM = OptGBM-源码

OptGBM OptGBM（= + ）提供了一种scikit-learn兼容的估算器，可通过Optuna调整LightGBM中的超参数。 例子 import optgbm as lgb from sklearn . datasets import load_boston reg = lgb . LGBMRegressor ( random_state = 0 ) X , y = load_boston ( return_X_y = True ) reg . fit ( X , y ) y_pred = reg . predict ( X , y ) 默认情况下，将搜索以下超参数。 bagging_fraction bagging_freq feature_fractrion lambda_l1 lambda_l2 max_depth min_data_in_leaf
