Continual Learning using a Bayesian Nonparametric Dictionary of Weight Factors

AISTATS 2021poster

Naively trained neural networks tend to experience catastrophic forgetting in sequential task settings, where data from previous tasks are unavailable. A number of methods, using various model expansion strategies, have been proposed recently as possible solutions. However, determining how much to e…

Perturbing Across the Feature Hierarchy to Improve Standard and Strict Blackbox Attack Transferability

NeurIPS 2020poster

We consider the blackbox transfer-based targeted adversarial attack threat model in the realm of deep neural network (DNN) image classifiers. Rather than focusing on crossing decision boundaries at the output layer of the source model, our method perturbs representations throughout the extracted fea…

Kernel-Based Approaches for Sequence Modeling: Connections to Neural Methods

NeurIPS 2019poster

We investigate time-dependent data analysis from the perspective of recurrent kernel machines, from which models with hidden units and gated memory cells arise naturally. By considering dynamic gating of the memory cell, a model closely related to the long short-term memory (LSTM) recurrent neural n…
