Survey: Leakage and Privacy at Inference Time

no code implementations4 Jul 2021 Marija Jegorova, Chaitanya Kaul, Charlie Mayor, Alison Q. O'Neil, Alexander Weir, Roderick Murray-Smith, Sotirios A. Tsaftaris

Leakage of data from publicly available Machine Learning (ML) models is an area of growing significance as commercial and government applications of ML can draw on multiple sources of data, potentially including users' and clients' sensitive data.

Similarity-based data mining for online domain adaptation of a sonar ATR system

no code implementations16 Sep 2020 Jean de Bodinat, Thomas Guerneve, Jose Vazquez, Marija Jegorova

Due to the expensive nature of field data gathering, the lack of training data often limits the performance of Automatic Target Recognition (ATR) systems.

Adversarial Generation of Informative Trajectories for Dynamics System Identification

1 code implementation2 Mar 2020 Marija Jegorova, Joshua Smith, Michael Mistry, Timothy Hospedales

Dynamic System Identification approaches usually heavily rely on the evolutionary and gradient-based optimisation techniques to produce optimal excitation trajectories for determining the physical parameters of robot platforms.

Full-Scale Continuous Synthetic Sonar Data Generation with Markov Conditional Generative Adversarial Networks

no code implementations15 Oct 2019 Marija Jegorova, Antti Ilari Karjalainen, Jose Vazquez, Timothy Hospedales

High-quality realistic sonar data simulation could be of benefit to multiple applications, including training of human operators for post-mission analysis, as well as tuning and validation of autonomous target recognition (ATR) systems for underwater vehicles.

Behavioural Repertoire via Generative Adversarial Policy Networks

no code implementations7 Nov 2018 Marija Jegorova, Stéphane Doncieux, Timothy Hospedales

Leveraging our generative policy network, a robot can sample novel behaviors until it finds one that works for a new environment.
