Training-Free Action Recognition and Goal Inference with Dynamic Frame Selection

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

We introduce VidTFS, a Training-free, open-vocabulary video goal and action inference framework that combines the frozen vision foundational model (VFM) and large language model (LLM) with a novel dynamic Frame Selection module.

PDPGD: Primal-Dual Proximal Gradient Descent Adversarial Attack

3 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.

Improved Network Robustness with Adversary Critic

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.
