The moving average of the estimated Hessian, followed by element-wise clipping. The update is the moving average of the gradients divided by Optimizer that uses a light-weight estimate of the diagonal Hessian as the Second-order Clipped Stochastic Optimization, a simple scalable second-order Adam and its variants have been state-of-the-artįor years, and more sophisticated second-order (Hessian-based) optimizers often Improvement of the optimization algorithm would lead to a material reduction on Download a PDF of the paper titled Sophia: A Scalable Stochastic Second-order Optimizer for Language Model Pre-training, by Hong Liu and 4 other authors Download PDF Abstract: Given the massive cost of language model pre-training, a non-trivial
