Segmentation analysis and the recovery of queuing parameters via the Wasserstein distance: a study of administrative data for patients with chronic obstructive pulmonary disease

no code implementations10 Aug 2020 Henry Wilde, Vincent Knight, Jonathan Gillard, Kendal Smith

This work uses a data-driven approach to analyse how the resource requirements of patients with chronic obstructive pulmonary disease (COPD) may change, quantifying how those changes impact the hospital system with which the patients interact.

A novel initialisation based on hospital-resident assignment for the k-modes algorithm

no code implementations7 Feb 2020 Henry Wilde, Vincent Knight, Jonathan Gillard

This paper presents a new way of selecting an initial solution for the k-modes algorithm that allows for a notion of mathematical fairness and a leverage of the data that the common initialisations from literature do not.

Evolutionary Dataset Optimisation: learning algorithm quality through evolution

no code implementations31 Jul 2019 Henry Wilde, Vincent Knight, Jonathan Gillard

We instead aim to gain a richer picture of the performance of an algorithm by generating artificial data through genetic evolution, the purpose of which is to create populations of datasets for which a particular algorithm performs well on a given metric.

An Evolutionary Game Theoretic Model of Rhino Horn Devaluation

1 code implementation20 Dec 2017 Nikoleta E. Glynatsi, Vincent Knight, Tamsin E. Lee

The purpose of this work is to discover whether conditions which encourage the poachers to behave selectively exist, that is, they only kill those rhinos with full horns.

Reinforcement Learning Produces Dominant Strategies for the Iterated Prisoner's Dilemma

1 code implementation19 Jul 2017 Marc Harper, Vincent Knight, Martin Jones, Georgios Koutsovoulos, Nikoleta E. Glynatsi, Owen Campbell

We present tournament results and several powerful strategies for the Iterated Prisoner's Dilemma created using reinforcement learning techniques (evolutionary and particle swarm algorithms).

An open reproducible framework for the study of the iterated prisoner's dilemma

no code implementations4 Apr 2016 Vincent Knight, Owen Campbell, Marc Harper, Karol Langner, James Campbell, Thomas Campbell, Alex Carney, Martin Chorley, Cameron Davidson-Pilon, Kristian Glass, Nikoleta Glynatsi, Tomáš Ehrlich, Martin Jones, Georgios Koutsovoulos, Holly Tibble, Müller Jochen, Geraint Palmer, Piotr Petunov, Paul Slavin, Timothy Standen, Luis Visintini, Karl Molden

With a growing collection of 139 strategies, the library is a also a platform for an original tournament that, in itself, is of interest to the game theoretic community.
