A Law of Robustness for Weight-bounded Neural Networks

no code implementations16 Feb 2021 Hisham Husain, Borja Balle

Our result coincides with that conjectured in (Bubeck et al., 2020) for two-layer networks under the assumption of bounded weights.

Regularized Policies are Reward Robust

no code implementations18 Jan 2021 Hisham Husain, Kamil Ciosek, Ryota Tomioka

Entropic regularization of policies in Reinforcement Learning (RL) is a commonly used heuristic to ensure that the learned policy explores the state-space sufficiently before overfitting to a local optimal policy.

Fair Densities via Boosting the Sufficient Statistics of Exponential Families

1 code implementation1 Dec 2020 Alexander Soen, Hisham Husain, Richard Nock

Furthermore, when the weak learners are specified to be decision trees, the sufficient statistics of the learned distribution can be examined to provide clues on sources of (un)fairness.

Optimal Continual Learning has Perfect Memory and is NP-hard

no code implementations ICML 2020 Jeremias Knoblauch, Hisham Husain, Tom Diethe

Continual Learning (CL) algorithms incrementally learn a predictor or representation across multiple sequentially observed tasks.

Distributional Robustness with IPMs and links to Regularization and GANs

no code implementations NeurIPS 2020 Hisham Husain

Our main result shows that DRO under \textit{any} choice of IPM corresponds to a family of regularization penalties, which recover and improve upon existing results in the setting of MMD and Wasserstein distances.

A Primal-Dual link between GANs and Autoencoders

no code implementations NeurIPS 2019 Hisham Husain, Richard Nock, Robert C. Williamson

First, we find that the $f$-GAN and WAE objectives partake in a primal-dual relationship and are equivalent under some assumptions, which then allows us to explicate the success of WAE.

Adversarial Networks and Autoencoders: The Primal-Dual Relationship and Generalization Bounds

no code implementations3 Feb 2019 Hisham Husain, Richard Nock, Robert C. Williamson

First, we find that the $f$-GAN and WAE objectives partake in a primal-dual relationship and are equivalent under some assumptions, which then allows us to explicate the success of WAE.

Integral Privacy for Sampling

1 code implementation13 Jun 2018 Hisham Husain, Zac Cranko, Richard Nock

Privacy enforces an information theoretic barrier on approximation, and we show how to reach this barrier with guarantees on the approximation of the target non private density.
