New neural method improves Legendre-Fenchel transform accuracy

Researchers have developed a new method for approximating the Legendre-Fenchel transform, a key tool in convex analysis and machine learning. Their approach utilizes neural networks and introduces a Hessian-based preconditioning strategy to improve accuracy, especially for ill-conditioned functions. This method involves an affine deformation around a function's minimizer, simplifying the conjugation map and allowing a residual network to learn it more effectively. Experiments show enhanced convergence rates and numerical accuracy, particularly for challenging problems, with minimal computational overhead. AI
