Understanding LightGBM Parameters (and How to Tune Them)

WebDec 22, 2024 · LightGBM splits the tree leaf-wise as opposed to other boosting algorithms that grow tree level-wise. It chooses the leaf with maximum delta loss to grow. Since the leaf is fixed, the leaf-wise algorithm has lower loss compared to the level-wise algorithm. http://duoduokou.com/python/40872197625091456917.html tower trailer official https://rjrspirits.com
