The neural network classifier, an efficient pattern recognition approach, was used to classify normal and malignant cells based on the extracted multifractal features. The application of self-organization map yielded high rates of correct classification at both the cell level and the patient level. These results indicate that the use of intelligent computational techniques along with multifractal features may offer very useful information about the potential of malignancy of cervical cells.","PeriodicalId":131657,"journal":{"name":"2007 Siberian Conference on Control and Communications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116553532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
