Original PSO algorithm could be trapped in the local minima easily, so in this paper we improved the original PSO algorithm using the idea of simulated annealing algorithm, which makes the PSO algorithm jump out of local minima. In this paper, two improved strategies was proposed, and after testing and comparing the two improved algorithms with the original PSO algorithm again and again, we conclude at last that efficiency of searching global about the two improved strategies is better than the original PSO.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123455588","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}

We present harmony search algorithm for feature selection for image steganalysis. Experiment show that the proposed hybrid algorithm for feature selection increases the testing accuracy of classifying result. The combination of the feature set extracted is likely to improve the performance of general steganalysis methods which have more real value for deterring covert communications and the uncorrelated features extracted contain more discriminatory information when distinguish different kinds of steganography.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114080401","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 this paper, a prediction model of time series based on RBF neural network (RBFNN) is proposed to learn the priori knowledge of background machine noise that obscure in a template noise which is tailored from the historical samples of background machine noises. By defining the mean square error of prediction to candidate independent component with the proposed RBFNN model as the contrast function, a new ICA-R algorithm is proposed to extract the `pure' background machine noise which is then taken as reference input of a Volterra Adaptive Noise Cancellation (VANC) system. The simulation shows that the combination of ICA-R and VANC system prevails over a standard VANC system. The new VANC system is easier to be implemented in engineering applications due to its sensor-position independent characteristics.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124041622","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}

Although ACO can get solutions that are quite near to the optimal solution, it still has its own problems. Premature bogs the system down in a locally optimal solution rather than the global optimal one. To get better solutions, it requires a larger number of ants and iterations which consume more time. Parallelization is an effective way to solve large-scale ant colony optimization algorithms over large dataset. We propose a MapReduce based ACO approach. We show how ACO algorithms can be modeled into the MapReduce framework. We describe the algorithm design and implementation of ACO on Hadoop.","PeriodicalId":404981,"journal":{"name":"2012 8th International Conference on Natural Computation","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130695367","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}
