Abstract

Package confeito provides fast ensemble tree inference. See documents on GoDoc for details.

This package is based on QuickScorer [Lucchese+ 2015]. We confirmed that the QuickScorer-based implementation is several times faster than the naive implementation on 65536 depth-12 trees on 65536D dense feature vector (see benchmarks BenchmarkForest and BenchmarkBasicEnsembleTrees).
