WebJan 17, 2024 · LightGBMの特徴 ①予測精度が高い 一般的にディープラーニングを除いた機械学習の中ではXGBoostと並んで最高の予測精度。 ②モデルの訓練に掛かる時間が比較的短い 同等の予測精度を誇るXGBoostよりも計算コストが少ない。 （LightGBMが「Light（軽い）」と言われる所以。 ） ③過学習しやすい 複雑な決定木構造になるため、 … WebLightGBM constructs its data format, called a "Dataset", from tabular data. By default, that Dataset object on the R side does not keep a copy of the raw data. This reduces LightGBM's memory consumption, but it means that the Dataset object cannot be changed after it has been constructed. greenworks snow blower 40v at amazon https://vapourproductions.com
