In this talk, we introduce a novel computational model called Clustering Support Vector Machines (CSVMs) to deal with the complex classification problems in many applications with huge datasets. Taking advantage of both theory of granular computing and advanced statistical learning methodology, CSVMs are built specifically for each information granule partitioned intelligently by the clustering algorithm. This feature makes learning tasks for each CSVM more specific and simpler. Moreover, since a CSVM models each granule, the CSVM model can be easily parallelized and handle huge datasets efficiently. We apply this new model to the prediction of protein local tertiary structures. Compared with the conventional clustering method, the prediction accuracy has been improved noticeably when the new CSVM model is used.
