Local Convolutions Cause an Implicit Bias towards High Frequency Adversarial Examples

no code implementations19 Jun 2020 Josue Ortega Caro, Yilong Ju, Ryan Pyle, Sourav Dey, Wieland Brendel, Fabio Anselmi, Ankit Patel

Inspired by theoretical work on linear full-width convolutional models, we hypothesize that the local (i. e. bounded-width) convolutional operations commonly used in current neural networks are implicitly biased to learn high frequency features, and that this is one of the root causes of high frequency adversarial examples.

Deep Residual Autoencoders for Expectation Maximization-inspired Dictionary Learning

1 code implementation18 Apr 2019 Bahareh Tolooshams, Sourav Dey, Demba Ba

Specifically, we leverage the interpretation of the alternating-minimization algorithm for dictionary learning as an approximate Expectation-Maximization algorithm to develop autoencoders that enable the simultaneous training of the dictionary and regularization parameter (ReLU bias).
