• abstract = "This paper presents a genetic programming based approach for optimising the feature extraction step of a handwritten character recogniser. This recognizer uses a simple multilayer perceptron as a classifier and operates on a hierarchical feature space of orientation, curvature, and centre of mass primitives. The nodes of the hierarchy represent rectangular sub-regions of their parent node, the tree root corresponding to the character's bounding box. Within each sub-region, a variable number of fuzzy features are extracted. Genetic programming is used to simultaneously learn the best hierarchy and the best combination of fuzzy features. Moreover, the fuzzy features are not predetermined, they are inferred from the evolution process which runs a two-objective selection operator. The first objective maximises the recognition rate, and the second minimises the feature space size. Results on Unipen data show that, using this approach, robust representations could be obtained that out-performed comparable human-designed hierarchical fuzzy regional representations.",
