Dynamic Sparse Training with Structured Sparsity

1 code implementation3 May 2023 Mike Lasby, Anna Golubeva, Utku Evci, Mihai Nica, Yani Ioannou

Dynamic Sparse Training (DST) methods achieve state-of-the-art results in sparse neural network training, matching the generalization of dense models while enabling sparse training and inference.

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.

Measuring Neural Net Robustness with Constraints

1 code implementation NeurIPS 2016 Osbert Bastani, Yani Ioannou, Leonidas Lampropoulos, Dimitrios Vytiniotis, Aditya Nori, Antonio Criminisi

Despite having high accuracy, neural nets have been shown to be susceptible to adversarial examples, where a small perturbation to an input can cause it to become mislabeled.

Deep Roots: Improving CNN Efficiency with Hierarchical Filter Groups

no code implementations CVPR 2017 Yani Ioannou, Duncan Robertson, Roberto Cipolla, Antonio Criminisi

We propose a new method for creating computationally efficient and compact convolutional neural networks (CNNs) using a novel sparse connection structure that resembles a tree root.

Refining Architectures of Deep Convolutional Neural Networks

no code implementations CVPR 2016 Sukrit Shankar, Duncan Robertson, Yani Ioannou, Antonio Criminisi, Roberto Cipolla

Deep Convolutional Neural Networks (CNNs) have recently evinced immense success for various image recognition tasks.

Decision Forests, Convolutional Networks and the Models in-Between

1 code implementation3 Mar 2016 Yani Ioannou, Duncan Robertson, Darko Zikic, Peter Kontschieder, Jamie Shotton, Matthew Brown, Antonio Criminisi

We present a systematic analysis of how to fuse conditional computation with representation learning and achieve a continuum of hybrid models with different ratios of accuracy vs. efficiency.
