【问题描述】:
我已经安装了 XGBoost。 这些是它在执行时显示的参数: 打印(xgboost.XGBClassifier())
XGBClassifier(base_score=0.5, colsample_bylevel=1, colsample_bytree=1,
gamma=0, learning_rate=0.1, max_delta_step=0, max_depth=3,
min_child_weight=1, missing=None, n_estimators=100, nthread=-1,
objective='binary:logistic', reg_alpha=0, reg_lambda=1,
scale_pos_weight=1, seed=0, silent=True, subsample=1)
但是在Scikit-Learn API的文档中,出现了“助推器”参数。为什么我没有?
Scikit-Learn API
Scikit-Learn Wrapper interface for XGBoost.
class xgboost.XGBRegressor(max_depth=3, learning_rate=0.1,
n_estimators=100, silent=True, objective='reg:linear',
**booster='gbtree'**, nthread=-1, gamma=0, min_child_weight=1,
max_delta_step=0, subsample=1, colsample_bytree=1, colsample_bylevel=1,
reg_alpha=0, reg_lambda=1, scale_pos_weight=1, base_score=0.5, seed=0,
missing=None)
编辑
这是我得到的:
---------------------------------------------------------------------------
