According to Wikipedia "In computer science, counting sort is an algorithm for sorting a collection of objects according to keys that are small integers; that is, it is an integer sorting algorithm. It operates by counting the number of objects that have each distinct key value, and using ari...
更快的训练速度:LightGBM使用直方图算法(histogram algorithm),这种算法占用的内存更低,数据分割的复杂度更低,从而显著提高了训练速度。 更低的内存消耗:与XGBoost相比,LightGBM的内存占用率更低,大约是XGBoost的1/612。 更高的准确率:在保持或提升准确率的同时,LightGBM在许多实验中表现出色...
