Factored Evolutionary Algorithms
TL;DR: A formal definition of FEA algorithms is given and empirical results related to their performance are presented, showing that FEA’s performance is not restricted by the underlying optimization algorithm by creating FEA versions of hill climbing, particle swarm optimization, genetic algorithm, and differential evolution and comparing their performance to their single-population and cooperative coevolutionary counterparts.
Proceedings ArticleDOI
A New Discrete Particle Swarm Optimization Algorithm
TL;DR: This paper presents a version of PSO that is able to optimize over discrete variables, which is called Integer and Categorical PSO (ICPSO), and incorporates ideas from Estimation of Distribution Algorithms (EDAs) in that particles represent probability distributions rather than solution values, and the PSO update modifies the probability distributions.
Journal ArticleDOI
Abductive inference in Bayesian networks using distributed overlapping swarm intelligence
TL;DR: Several multi-swarm algorithms based on the overlapping swarm intelligence framework to find approximate solutions to the problems of full and partial abductive inference in Bayesian belief networks are proposed.
Proceedings ArticleDOI
Graph-based ontology-guided data mining for D-matrix model maturation
TL;DR: A maturation approach is proposed which uses the graph-theoretic representations of Timed Failure Propagation Graph models and diagnostic sessions based on recently standardized diagnostic ontologies to determine statistical discrepancies between that which is expected by the models and that which has been encountered in practice.
Proceedings ArticleDOI
Diagnostic alarm sequence maturation in timed failure propagation graphs
Shane Strasser,John W. Sheppard +1 more
TL;DR: Previous work in using historical maintenance and diagnostic information to identify potential errors in the TFPG-based diagnostic models and recommend ways of maturing these models are extended by extending the maturation process to incorporate historical alarm sequences and to model these sequences using a probabilistic transition matrix.
