Zero Shot Open-ended Video Inference

no code implementations23 Jan 2024 Ee Yeo Keat, Zhang Hao, Alexander Matyasko, Basura Fernando

Zero-shot open-ended inference on untrimmed videos poses a significant challenge, especially when no annotated data is utilized to navigate the inference direction.

PDPGD: Primal-Dual Proximal Gradient Descent Adversarial Attack

2 code implementations3 Jun 2021 Alexander Matyasko, Lap-Pui Chau

In this work, we introduce a fast, general and accurate adversarial attack that optimises the original non-convex constrained minimisation problem.

1 code implementation NeurIPS 2018 Alexander Matyasko, Lap-Pui Chau

Our main idea is: adversarial examples for the robust classifier should be indistinguishable from the regular data of the adversarial target.
