This method is often useful in understanding how a particular class of genes functions together during a biological process. In this study, we attempted to perform clustering using the Markov cluster (MCL) algorithm, a clustering method for graphs based on the simulation of stochastic flow. It is a fast and efficient algorithm that clusters nodes in a graph through simulation by computing probability. First, we converted the raw matrix into a sample matrix using the Euclidean distance of the genes between the samples. Second, we applied the MCL algorithm to the new matrix of Euclidean distance and considered 2 factors, namely, the inflation and diagonal terms of the matrix. We have turned to set the proper factors through massive experiments. In addition, distance thresholds, i.e., the average of each column data elements, were used to clearly distinguish between groups. Our experimental result shows about 70% accuracy in average compared to the class that is known before. We also compared the MCL algorithm with the self-organizing map (SOM) clustering, K-means clustering and hierarchical clustering (HC) algorithms.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121095744","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}

Like traditional Web objects, rich media objects can benefit from proxy caching, but caching streaming media is more of challenging than caching simple Web objects, because the streaming media have features such as huge size and high bandwidth. Due to huge size of streaming media, lots of researches manage the contents with segments for efficient storage management. And to support various bandwidth requirements for the heterogeneous ubiquitous devices, a transcoding proxy is usually necessary to provide not only adapting multimedia streams to the client by transcoding, but also caching them for later use. In this paper, we propose the hybrid segmentation strategy for the transcoding proxy that is uniform segmentation in the same version and is also exponential segmentation among the multiple versions. This strategy reduces the replacement count than uniform segmentation and gets the similar performance to uniform segmentation. The performance results show that hybrid segmentation with aggregated profit function have a high delay saving ratio, high byte-hit ratio and less transcoding data.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125216829","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}
