LightGBM: gradient-aware sampling and exclusive-feature bundling

Combined gradient-based one-side sampling with reweighting of small-gradient samples and greedy bundling of sparse, nearly exclusive features to reduce histogram-based tree-training cost.

Combined gradient-based one-side sampling with reweighting of small-gradient samples and greedy bundling of sparse, nearly exclusive features to reduce histogram-based tree-training cost.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

Inherits gradient boosting and histogram trees. GOSS approximates split gains under sampling/size conditions; EFB is lossless only for suitable exclusivity, with conflicts trading accuracy for speed. No unconditional constant-factor graph-coloring/bundling theorem or universal20xperformance claim exported from the paper's phrasing.2017paper differs from2016project establishment.
