The estimation of the classifier error plays a key role in accuracy-based learning classifier systems. In this paper we study the current definition of the classifier error in XCSF and discuss the limitations of the algorithm that is currently used to compute the classifier error estimate from online experience. Subsequently, we introduce a new definition for the classifier error and apply the Bayes...
This paper introduces a new variety of learning classifier system (LCS), called MILCS, which utilizes mutual information as fitness feedback. Unlike most LCSs, MILCS is specifically designed for supervised learning. We present preliminary results, and contrast them to results from XCS. We discuss the explanatory power of the resulting rule sets and introduce a new technique for visualizing explanatory...
Learning Classifier Systems use evolutionary algorithms to facilitate rule- discovery, where rule fitness is traditionally payoff based and assigned under a sharing scheme. Most current research has shifted to the use of an accuracy-based scheme where fitness is based on a rule’s ability to predict the expected payoff from its use. Learning Classifier Systems that build anticipations of the expected...
This article describes a learning classifier system (LCS) approach to relational reinforcement learning (RRL). The system, Foxcs-2, is a derivative of Xcs that learns rules expressed as definite clauses over first-order logic. By adopting the LCS approach, Foxcs-2, unlike many RRL systems, is a general, model-free and “tabula rasa” system. The change in representation from bit-strings in Xcs to first-order...
This paper reviews a competent Pittsburgh LCS that automatically mines important substructures of the underlying problems and takes problems that were intractable with first-generation Pittsburgh LCS and renders them tractable. Specifically, we propose a χ-ary extended compact classifier system (χeCCS) which uses (1) a competent genetic algorithm (GA) in the form of χ-ary extended compact genetic...
