Researchers have developed a new gradient-regularized Newton scheme to ensure global convergence for Gradient Boosting Decision Trees (GBDTs), a technique widely used in tabular machine learning. This method introduces an adaptive L2-regularization term, achieving a convergence rate comparable to first-order boosting methods like Nesterov momentum. Numerical experiments demonstrated that this new scheme converges where standard Newton boosting might diverge. Additionally, separate research presents a multimodal machine learning framework for diagnosing ejection fraction from ECGs, achieving high accuracy and providing explainable features. AI
