Deep Learning Dynamics: A Scientific Approach

摘要

In this talk, I will introduce my a series of works on understanding and improving deep learning via scientific principles and methodology. The success of deep learning depends on both neural networks and optimization dynamcis. I will visit several very foundamental issues in deep learning dynamics: (1) SGD Dynamics and how it selects flat minima; (2) Adam dynamics and how it explains the power of Adam; (3) improving deep learning from a optimization dynamical perspetive; (4) the overlooked pitfalls of weight decay and how to mitigate them; (5) a bridge between protein dynamics and deep learning dynamics. Through this talk, we will also see that scientific principles and theories can provide useful insights and tools for understanding and improving deep learning.
