Method and Apparatus for Deep Neural Network Training Using the Dynamic Spectral Optimizer (DSO).

Description: This invention introduces a method and apparatus that enhances the training of machine-learning models by estimating curvature information during each training step and transforming the loss gradient via Chebyshev second-kind polynomial filters. It selectively targets eigenvalue bands across the Hessian spectrum to improve training speed...
