Abstract

Recently, molecular simulations have benefited greatly from the development and subsequent application of deep-learning methods. In this talk, we will discuss how machine-learning methods can be combined with enhanced sampling techniques to speed up molecular dynamic simulations. We will then discuss about our recent effort on learning from Alphafold2 to reproduce and improve protein structure prediction AI models. All these methods are implemented in our home-made molecular simulation package, SPONGE, an MD software rewritten using MindSpore and highly compatible with the deep-learning platform. Through these efforts, we try to generate a multi-functional package for structure prediction, molecule and sequence generation, structure evaluation, and dynamics simulation. We will also discuss the possible applications of these methods in physical, chemical and biological problems.
