This paper describes an approach to the use of gradient descent search in genetic programming for continuously evolving genetic programs for object classification problems. An inclusion factor is introduced to each node in a genetic program and gradient descent search is applied to the inclusion factors. Three new on-zero operators and two new continuous(More)
We describe a semantically-based Web Map Mediation Service (WMMS) that allows researchers to define, capture and reuse semantic relationships between map categories, via a set of Web Services. A map can then be viewed according to different taxonomies or legends, whose categories have been semantically related to those native to the map. Such 'mappings' or(More)
