LipschitzLR: Using theoretically computed adaptive learning rates for fast convergence

APPLIED INTELLIGENCE, 51(3), 1460–1478.

By: R. Yedida n, S. Saha & T. Prashanth*

Contributors: R. Yedida n, S. Saha & T. Prashanth*

author keywords: Lipschitz constant; Adaptive learning; Machine learning; Deep learning
TL;DR: A novel theoretical framework for computing large, adaptive learning rates makes minimal assumptions on the activations used and exploits the functional properties of the loss function and shows that the inverse of the Lipschitz constant is an ideal learning rate. (via Semantic Scholar)
