The number of image features used by content-based remote sensing image retrieval (CBRSIR) system is not less than one hundred, and the image amount is very large, at the same time, the time cost is very important to the retrieval system. So the image feature compression is a crucial subject to CBRSIR. This paper proposed a high dimensional feature’s compression approach based on discrete parti...

This article proposes the use of a discrete version of the well known Particle Swarm Optimization, DPSO, a metaheuristic optimization algorithm for numerically solving a system of linear Diophantine equations. Likewise, the transformation of this type of problem (i.e. solving a system of equations) into an optimization one is also shown. The current algorithm is able to find all the integer roo...

This paper presents and discusses the results produced by the MapPSO system for the 2010 Ontology Alignment Evaluation Initiative (OAEI). MapPSO is an ontology alignment approach based on discrete particle swarm optimisation (DPSO). Firstly, specific characteristics of the MapPSO system and their relation to the results obtained in the OAEI are discussed. Secondly, the results for the benchmark...

When an enterprise has thousands of varieties in its inventory, the use of a single management method could not be a feasible approach. A better way to manage this problem would be to categorise inventory items into several clusters according to inventory decisions and to use different management methods for managing different clusters. The present study applies DPSO (dynamic particle swarm opt...

Based on the research and development about Web service, the business platform topology of ac-service flow is deepened from architecture-centric perspective. For Web service’s dynamic composition and self-adaptation meeting user requirement, architecture-centric merging among flows is put forward, in order to get this goal, optimizing previous flow granularities’ selection and composition. To s...
