An Experimentation Platform for Explainable Coalition Situational Understanding

no code implementations27 Oct 2020 Katie Barrett-Powell, Jack Furby, Liam Hiley, Marc Roig Vilamala, Harrison Taylor, Federico Cerutti, Alun Preece, Tianwei Xing, Luis Garcia, Mani Srivastava, Dave Braines

We present an experimentation platform for coalition situational understanding research that highlights capabilities in explainable artificial intelligence/machine learning (AI/ML) and integration of symbolic and subsymbolic AI/ML approaches for event processing.

Explaining Motion Relevance for Activity Recognition in Video Deep Learning Models

no code implementations31 Mar 2020 Liam Hiley, Alun Preece, Yulia Hicks, Supriyo Chakraborty, Prudhvi Gurram, Richard Tomsett

Our results show that the selective relevance method can not only provide insight on the role played by motion in the model's decision -- in effect, revealing and quantifying the model's spatial bias -- but the method also simplifies the resulting explanations for human consumption.

Explainable Deep Learning for Video Recognition Tasks: A Framework & Recommendations

no code implementations7 Sep 2019 Liam Hiley, Alun Preece, Yulia Hicks

This paper seeks to highlight the need for explainability methods designed with video deep learning models, and by association spatio-temporal input in mind, by first illustrating the cutting edge for video deep learning, and then noting the scarcity of research into explanations for these methods.

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.
