Deep Learning Theory Review: An Optimal Control and Dynamical Systems Perspective

Liu, Guan-Horng, Theodorou, Evangelos A.

Understand

Attempts from different disciplines to provide a fundamental understanding of deep learning have advanced rapidly in recent years, yet a unified framework remains relatively limited.

  • In this article, we provide one possible way to align existing branches of deep learning theory through the lens of dynamical system and optimal control.
  • By viewing deep neural networks as discrete-time nonlinear dynamical systems, we can analyze how information propagates through layers using mean field theory.
  • When optimization algorithms are further recast as controllers, the ultimate goal of training processes can be formulated as an optimal control problem.
