This work proposes a method which enables us to perform kernel Fisher discriminant analysis in the whole
eigenspace for face recognition. It employs the ratio of eigenvalues to decompose the entire kernel feature space into two subspaces: a reliable... Read More about Kernel Fisher Discriminant Analysis in Full Eigenspace.

Environmental adversity and uncertainty favour cooperation. (2007)
Journal Article
(2007). Environmental adversity and uncertainty favour cooperation. BMC Evolutionary Biology, 240 - ?. https://doi.org/10.1186/1471-2148-7-240

BACKGROUND: A major cornerstone of evolutionary biology theory is the explanation of the emergence of cooperation in communities of selfish individuals. There is an unexplained tendency in the plant and animal world - with examples from alpine plants... Read More about Environmental adversity and uncertainty favour cooperation..

Linear and nonlinear wave propagation in coated or uncoated elastic half-spaces (2007)
Book Chapter
(2007). Linear and nonlinear wave propagation in coated or uncoated elastic half-spaces. In Waves in Nonlinear Pre-Stressed Materials (103-127)

In these lectures, we discuss three closely related topics. We first discuss derivation of the nonlinear evolution equation for surface acoustic waves and show that all known methods of derivation should and do give the same evolution equation. We th...

This paper investigates the method for object fingerprinting in the context of element specific x-ray imaging. In particular, the use of spectral descriptors that are illumination invariant and viewpoint independent for pattern identification was exa...

In this paper, we consider decidability questions that are related to the membership problem in matrix semigroups. In particular, we consider the membership of a given invertible diagonal matrix in a matrix semigroup and then a scalar matrix, which h...

Both reactive and deliberative qualities are essential for a good action selection mechanism. We present a model that embodies a hybrid of two very different neural network architectures inside an animat: one that controls their high level deliberati...

(2007). Infinity. In Philosophy of Logic, vol. 5 of the Handbook of the Philosophy of Science (523 -585)

This essay surveys the different types of infinity that occur in pure and applied mathematics, with emphasis on: 1. the contrast between potential infinity and actual infinity; 2. Cantor's distinction between transfinite sets and absolute infinity; 3... Read More about Infinity.

Unbounded Evolutionary Dynamics in a System of Agents that Actively Process and Transform Their Environment (2006)

Bedau et al.'s statistical classification system for long-term evolutionary dynamics provides a test for open-ended evolution. Making this test more rigorous, and passing it, are two of the most important open problems for research into systems of ag...

The N-strikes-out algorithm: A steady-state algorithm for coevolution (2006)
Journal Article
Channon. (2006). The N-strikes-out algorithm: A steady-state algorithm for coevolution

We introduce the N-strikes-out algorithm, a simple steady-state genetic algorithm for competitive coevolution. The algorithm can be summarised as follows: Run competitions between randomly chosen individuals, keep track of the number of defeats for e...

Analysing co-evolution among artificial 3D creatures (2006)
Book Chapter
Channon. (2006). Analysing co-evolution among artificial 3D creatures. In Lecture Notes in Computer Science (167 -178)

This paper is concerned with the analysis of coevolutionary dynamics among 3D artificial creatures, similar to those introduced by Sims (1). Coevolution is subject to complex dynamics which are notoriously difficult to analyse. We introduce an improv... Read More about Analysing co-evolution among artificial 3D creatures.

Improved Bayesian Approach for Face Recognition (2005)
Presentation / Conference Contribution
Jiang, X.-D., Mandal, B., & Kot, A. (2005, December). Improved Bayesian Approach for Face Recognition. Presented at International Conference on Information, Communications and Signal Processing, Bangkok, Thailand

In subspace face recognition, PCA, LDA and Bayesian are the most commonly used methods. Each of them has their own advantages and disadvantages in recognizing human faces. Their recognition rates depend much on the methodologies used in selecting/tra... Read More about Improved Bayesian Approach for Face Recognition.

Thesis
Jayousi, R. An agent based co-operative preference model. (Thesis). Keele University. https://keele-repository.worktribe.com/output/1020265

Distributed problem solving is often characterised by multiple valid solutions, a solution being considered to be valid if it meets all the constraints. When there are multiple valid solutions, the user has a choice, which can be specified in terms o... Read More about An agent based co-operative preference model.
