Adversarial Augmentation Training Makes Action Recognition Models More Robust to Realistic Video Distribution Shifts

no code implementations21 Jan 2024 Kiyoon Kim, Shreyank N Gowda, Panagiotis Eustratiadis, Antreas Antoniou, Robert B Fisher

More precisely, we created dataset splits of HMDB-51 or UCF-101 for training, and Kinetics-400 for testing, using the subset of the classes that are overlapping in both train and test datasets.

Is Scaling Learned Optimizers Worth It? Evaluating The Value of VeLO's 4000 TPU Months

no code implementations27 Oct 2023 Fady Rezk, Antreas Antoniou, Henry Gouk, Timothy Hospedales

We analyze VeLO (versatile learned optimizer), the largest scale attempt to train a general purpose "foundational" optimizer to date.

Challenges of building medical image datasets for development of deep learning software in stroke

no code implementations26 Sep 2023 Alessandro Fontanella, Wenwen Li, Grant Mair, Antreas Antoniou, Eleanor Platt, Chloe Martin, Paul Armitage, Emanuele Trucco, Joanna Wardlaw, Amos Storkey

Despite the large amount of brain CT data generated in clinical practice, the availability of CT datasets for deep learning (DL) research is currently limited.

ACAT: Adversarial Counterfactual Attention for Classification and Detection in Medical Imaging

1 code implementation27 Mar 2023 Alessandro Fontanella, Antreas Antoniou, Wenwen Li, Joanna Wardlaw, Grant Mair, Emanuele Trucco, Amos Storkey

We investigate the best way to generate the saliency maps employed in our architecture and propose a way to obtain them from adversarially generated counterfactual images.

Contrastive Meta-Learning for Partially Observable Few-Shot Learning

1 code implementation30 Jan 2023 Adam Jelley, Amos Storkey, Antreas Antoniou, Sam Devlin

We evaluate our approach on an adaptation of a comprehensive few-shot learning benchmark, Meta-Dataset, and demonstrate the benefits of POEM over other meta-learning methods at representation learning from partial observations.

Data Augmentation Generative Adversarial Networks

7 code implementations ICLR 2018 Antreas Antoniou, Amos Storkey, Harrison Edwards

The model, based on image conditional Generative Adversarial Networks, takes data from a source domain and learns to take any data item and generalise it to generate other within-class data items.
