Apple Tasting Revisited: Bayesian Approaches to Partially Monitored Online Binary Classification

no code implementations29 Sep 2021 James A. Grant, David S. Leslie

We consider a variant of online binary classification where a learner sequentially assigns labels ($0$ or $1$) to items with unknown true class.

Learning to Rank under Multinomial Logit Choice

no code implementations7 Sep 2020 James A. Grant, David S. Leslie

The learning to rank (LTR) framework models this problem as a sequential problem of selecting lists of content and observing where users decide to click.

Filtered Poisson Process Bandit on a Continuum

no code implementations20 Jul 2020 James A. Grant, Roberto Szechtman

We consider a version of the continuum armed bandit where an action induces a filtered realisation of a non-homogeneous Poisson process.

Adaptive Sensor Placement for Continuous Spaces

no code implementations16 May 2019 James A. Grant, Alexis Boukouvalas, Ryan-Rhys Griffiths, David S. Leslie, Sattar Vakili, Enrique Munoz de Cote

We consider the problem of adaptively placing sensors along an interval to detect stochastically-generated events.

Adaptive Policies for Perimeter Surveillance Problems

no code implementations4 Oct 2018 James A. Grant, David S. Leslie, Kevin Glazebrook, Roberto Szechtman, Adam N. Letchford

Maximising the detection of intrusions is a fundamental and often critical aim of perimeter surveillance.

Combinatorial Multi-Armed Bandits with Filtered Feedback

no code implementations26 May 2017 James A. Grant, David S. Leslie, Kevin Glazebrook, Roberto Szechtman

Motivated by problems in search and detection we present a solution to a Combinatorial Multi-Armed Bandit (CMAB) problem with both heavy-tailed reward distributions and a new class of feedback, filtered semibandit feedback.
