From lightgbm import lgbmclassifier出错
WebThe power of the LightGBM algorithm cannot be taken lightly (pun intended). LightGBM is a distributed and efficient gradient boosting framework that uses tree-based learning. It’s histogram-based and places continuous values into discrete bins, which leads to faster training and more efficient memory usage. In this piece, we’ll explore ... Web6.1 LightGBM与XGBoost的联系和区别有哪些？. （1）LightGBM使用了基于histogram的决策树算法，这一点不同于XGBoost中的贪心算法和近似算法，histogram算法在内存和计算代价上都有不小优势。. 1）内存上优势：很明显，直方图算法的内存消耗为 (\#data* \#features * 1Bytes) (因为 ...
