Evolution with recombination as a Metropolis-Hastings sampling procedure

no code implementations9 Nov 2022 Jenny M. Poulton, Lee Altenberg, Chris Watkins

We derive a general and exact relationship between fitness fluctuations and response to selection.

A review of smartphones based indoor positioning: challenges and applications

no code implementations3 Jun 2020 Khuong An Nguyen, Zhiyuan Luo, Guang Li, Chris Watkins

The continual proliferation of mobile devices has encouraged much effort in using the smartphones for indoor positioning.

A Metric Learning Approach to Anomaly Detection in Video Games

1 code implementation20 May 2020 Benedict Wilkins, Chris Watkins, Kostas Stathis

With the aim of designing automated tools that assist in the video game quality assurance process, we frame the problem of identifying bugs in video games as an anomaly detection (AD) problem.

An evolutionary model that satisfies detailed balance

no code implementations27 Feb 2019 Jüri Lember, Chris Watkins

In those models, a new genome is born according to the breeding process, and then a genome is removed according to the selection scheme that involves fitness.

Sex as Gibbs Sampling: a probability model of evolution

no code implementations12 Feb 2014 Chris Watkins, Yvonne Buttkewitz

We show that evolutionary computation can be implemented as standard Markov-chain Monte-Carlo (MCMC) sampling.
