Bounding generalization error with input compression: An empirical study with infinite-width networks

no code implementations19 Jul 2022 Angus Galloway, Anna Golubeva, Mahmoud Salem, Mihai Nica, Yani Ioannou, Graham W. Taylor

Estimating the Generalization Error (GE) of Deep Neural Networks (DNNs) is an important task that often relies on availability of held-out data.

Monitoring Shortcut Learning using Mutual Information

no code implementations27 Jun 2022 Mohammed Adnan, Yani Ioannou, Chuan-Yung Tsai, Angus Galloway, H. R. Tizhoosh, Graham W. Taylor

The failure of deep neural networks to generalize to out-of-distribution data is a well-known problem and raises concerns about the deployment of trained networks in safety-critical domains such as healthcare, finance and autonomous vehicles.

Batch Normalization is a Cause of Adversarial Vulnerability

no code implementations6 May 2019 Angus Galloway, Anna Golubeva, Thomas Tanay, Medhat Moussa, Graham W. Taylor

Batch normalization (batch norm) is often used in an attempt to stabilize and accelerate training in deep neural networks.

Adversarial Examples as an Input-Fault Tolerance Problem

1 code implementation30 Nov 2018 Angus Galloway, Anna Golubeva, Graham W. Taylor

We analyze the adversarial examples problem in terms of a model's fault tolerance with respect to its input.

A Rate-Distortion Theory of Adversarial Examples

no code implementations27 Sep 2018 Angus Galloway, Anna Golubeva, Graham W. Taylor

The generalization ability of deep neural networks (DNNs) is intertwined with model complexity, robustness, and capacity.

Adversarial Training Versus Weight Decay

2 code implementations10 Apr 2018 Angus Galloway, Thomas Tanay, Graham W. Taylor

Performance-critical machine learning models should be robust to input perturbations not seen during training.

Predicting Adversarial Examples with High Confidence

no code implementations13 Feb 2018 Angus Galloway, Graham W. Taylor, Medhat Moussa

It has been suggested that adversarial examples cause deep learning models to make incorrect predictions with high confidence.

The Ciona17 Dataset for Semantic Segmentation of Invasive Species in a Marine Aquaculture Environment

no code implementations18 Feb 2017 Angus Galloway, Graham W. Taylor, Aaron Ramsay, Medhat Moussa

An original dataset for semantic segmentation, Ciona17, is introduced, which to the best of the authors' knowledge, is the first dataset of its kind with pixel-level annotations pertaining to invasive species in a marine environment.
