lightgbm的sklearn接口和原生接口参数详细说明及调参指点

class lightgbm.LGBMClassifier(boosting_type=‘gbdt‘, num_leaves=31, max_depth=-1, learning_rate=0.1, n_estimators=10, max_bin=255, subsample_for_bin=200000, objective=None, min_split_gain=0.0, min_child_weight=0.001, min_child_samples=20, subsample=1.0, subsample_freq=1, colsample_bytree=1.0, reg_alpha=0.0, reg_lambda=0.0, random_state=None, n_jobs=-1, silent=True, **kwargs)

boosting_type:default="gbdt"
　　　　　　　　 "gbdt":Gradient Boosting Decision Tree
　　　　　　　　 "dart":Dropouts meet Multiple Additive Regression Trees
　　　　　　　　 "goss":Gradient-based One-Side Sampling
　　　　　　　　 "rf": Random Forest

num_leaves (int, optional (default=31))：每个基学习器的最大叶子节点



max_depth (int, optional (default=-1))：每个基学习器的最大深度, -1 means no limit.
