Through dynamical stability analysis on various computer vision models, we find direct evidence that optimal deep neural network performance occur near the transition point separating stable and chaotic attractors. In fact modern neural network archivectures push the model closer to this edge of chaos during the training process.

Motivated by the edge of chaos principle behind the optimal performance of neural networks, we study the role of various hyperparameters in modern neural network training algorithms in terms of the order-chaos phase diagram.

C H Lai studied at The University of Chicago for both his undergraduate and graduate degrees. His PhD thesis research was in weak interactions phenomenology, carried out at the Fermi National Accelerator Laboratory , Batavia, Illinois, under the supervision of Chris Quigg .

Lai Choy Heng is Professor of Physics and the former Executive Vice-President, Yale-NUS Grad. Medical School College and Vice Provost at the National University of Singapore. He received his undergraduate as well as graduate degrees from the University of Chicago.

Emeritus Professor Bernard Tan remembered Prof Lai as a calm and mature character who can strike conversation on any diverse topics from music to politics. Prof Lai had played a major role in advancing the interests in various fields in physics especially in the application of …
