Hinge Regression Tree offers novel Newton method for oblique regression tree splitting

Researchers have introduced the Hinge Regression Tree (HRT), a novel method for creating oblique regression trees. HRT reframes the split-finding process as a non-linear least-squares problem, enabling efficient optimization through a damped Newton method. The paper demonstrates that HRT's model class is a universal approximator and shows competitive performance against existing single-tree baselines on various benchmarks. AI
