Researchers have developed a new parametric approach to piecewise linear regression in high dimensions using a method called Adaptive Block Gradient Descent (ABGD). This algorithm utilizes the difference of max-affine (DoMA) functions to represent piecewise linear models. The paper provides a theoretical analysis of ABGD's convergence and sample complexity, demonstrating its efficiency and optimality under certain conditions. AI
