Researchers have developed Hinge Regression Trees (HRT) and HRT-Boost, a new framework for creating compact tabular models. HRT reframes oblique split optimization as a nonlinear least-squares problem, allowing for a Newton method interpretation and theoretical guarantees of approximation. HRT-Boost builds on this by creating synergistic ensembles that offer empirical risk reduction. Evaluations show HRT performs competitively with existing single-tree methods, while HRT-Boost rivals strong ensemble baselines and often produces more compact models. AI
