AutoAttacker: A Large Language Model Guided System to Implement Automatic Cyber-attacks

no code implementations2 Mar 2024 Jiacen Xu, Jack W. Stokes, Geoff McDonald, Xuesong Bai, David Marshall, Siyue Wang, Adith Swaminathan, Zhou Li

Large language models (LLMs) have demonstrated impressive results on natural language tasks, and security researchers are beginning to employ them in both offensive and defensive systems.

TranSalNet: Towards perceptually relevant visual saliency prediction

1 code implementation7 Oct 2021 Jianxun Lou, Hanhe Lin, David Marshall, Dietmar Saupe, Hantao Liu

Due to the inherent inductive biases of CNN architectures, there is a lack of sufficient long-range contextual encoding capacity.

Gradient Weighted Superpixels for Interpretability in CNNs

no code implementations16 Aug 2019 Thomas Hartley, Kirill Sidorov, Christopher Willis, David Marshall

As Convolutional Neural Networks embed themselves into our everyday lives, the need for them to be interpretable increases.

Discriminating Spatial and Temporal Relevance in Deep Taylor Decompositions for Explainable Activity Recognition

4 code implementations5 Aug 2019 Liam Hiley, Alun Preece, Yulia Hicks, David Marshall, Harrison Taylor

However, by exploiting a simple technique that removes motion information, we show that it is not the case that this technique is effective as-is for representing relevance in non-image tasks.

Weakly-Supervised Temporal Localization via Occurrence Count Learning

no code implementations17 May 2019 Julien Schroeter, Kirill Sidorov, David Marshall

We propose a novel model for temporal detection and localization which allows the training of deep neural networks using only counts of event occurrences as training labels.

Temporal Localization

Detecting Violent and Abnormal Crowd activity using Temporal Analysis of Grey Level Co-occurrence Matrix (GLCM) Based Texture Measures

no code implementations17 May 2016 Kaelon Lloyd, David Marshall, Simon C. Moore, Paul L. Rosin

We utilise computer vision techniques to develop an automated method of abnormal crowd detection that can aid a human operator in the detection of violent behaviour.
