Combination of multiple classifiers can make full use of the complementary of the existing classifiers, thus owns better classification performance. A novel multiple classifiers based on C5.0 decision tree is proposed. It reduces the hyperspectral dimension through wavelet-PCA transform algorithm firstly. Then three supervised classifiers, namely Minimum Distance, Maximum Likelihood and SVM, combined by C5.0 decision tree, are used to realize hyperspectral classification. Experiments based on AVIRIS hyperspectral image data show that higher classification accuracy may be achieved via the multiple combined classifiers than a single sub-classifier. The proposed method can reduce the dimension of features and improve the classification performance efficiently.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130947946","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}

In order to help web providers select the appropriate pair of scheduling algorithm and cache replacement algorithm, and to help researchers evaluate new scheduling algorithm or cache replacement algorithm under different client access patterns, this paper designs and implements a trace-driven scheduling algorithm and cache replacement algorithm simulation platform based on JavaSim for web server cluster, called WSCSim. It models the serving time of static and dynamic requests respectively according to their deferent traits, supports traces of different formats, and can simulate complicated algorithms for Java's powerful function. In WSCSim, trace parser, distribution, scheduling algorithm and cache replacement algorithm are extensible; therefore user can add new components to the platform. Especially, Java interface and Java dynamic proxy technique are used to guarantee the Plug and Play (PnP) characteristic of these extensible components. Simulation tests show the feasibility and validity of WSCSim.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130084227","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}

For the time being, mammographic screening remains the most effective method for early detection of breast cancer. However, reading mammography is a time-consume error-prone work. Therefore, many computer-aided detection and diagnosis systems (CAD) have been developed to assist radiologists in detecting and classifying mammographic mass. Most of those CAD system used single classifier for the classification of mass patterns into benign and malignant, or normal and mass or calcification. Increasing number of researches demonstrated that multi-classifier is an effective approach to improve the classification performance of CAD system. In this paper, we present a new hybrid classifier for mammographic CAD by hybridizing Logistic Regression (LR) and K-nearest neighbor (KNN) classifiers. To test and evaluate the proposed hybrid classifier, several experiments were carried out. The experimental results show that the proposed hybrid method achieves better performance then those two single classifiers (i.e., LR classifier and KNN classifier).","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127921879","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}
