##Statistics Seminar##\\ Department of Mathematics and Statistics ^ **DATE:**|Thursday, April 13, 2022 | ^ **TIME:**|1:15pm -- 2:15pm | ^ **LOCATION:**|WH 100E | ^ **SPEAKER:**|Wei Yang, Binghamton University | ^ **TITLE:**|Unitary Neural Networks | \\ **Abstract** Vanishing / exploding gradient problem often arises in training deep neural networks. One way to make the neural network more stable is to replace the weight matrices Unitary / Orthogonal matrices. But this comes with the cost of a more expensive training cost. We will study some applications and methods of training in the literature.
