WebGradient boosting decision tree (GBDT) [1] is a widely-used machine learning algorithm, due to its efficiency, accuracy, and interpretability. GBDT achieves state-of-the-art performances in many machine learning tasks, such as multi-class classification [2], click prediction [3], and learning to rank [4]. WebThis article analyzed 850,660 data recorded by a wind farm from March 01, 2024, 00:00:00 to December 31, t2024, 23:50:00 were analyzed. And by using machine learning and extra tree, light gradient boosting machine, gradient boosting regressor, decision tree, Ada Boost, and ridge algorithms, the production power of the wind farm was predicted. country heat before and after
