rough classification
1.A Rough-Classification Method for the Recognition of Handwritten Chinese Characters
2.The model made rough classification to the human ears first according to their geometric features, then ICA was used to extract the algebra features and support vector machine (SVM) was for detailed classification, finally the results were achieved, which was in accordance with human natural recognition process.
5.The application of the rough set theory for image classification is to utilize equivalence relation classes through attribution reduction and decision rule reduction, and to obtain knowledge and the reduction of knowledge in the case of keeping the same ability for classification.
