Google's Yggdrasil Decision Forests boosted by new histogram techniques

Researchers have developed vectorized dynamic histograms to significantly speed up the training of sparse oblique (SPO) decision forests. These new methods, integrated into Google's Yggdrasil Decision Forests library, improve training efficiency by up to 2x for SPO-RF and 1.6x for SPO-GBT, making SPO-RF training time comparable to axis-aligned random forests. The optimizations were evaluated on extensive datasets and the implementation has been open-sourced. AI

IMPACT Accelerates training for sparse oblique decision forests, potentially enabling more complex models and faster iteration in machine learning applications.
