In this paper, we consider the estimation of the data model of ICA when Gaussian noise is present and the independent components are time dependent. The temporal dependencies are explained by assuming that each source is an autoregressive (AR) process and innovations are independently and identically distributed (i.i.d). A fixed-point algorithm to estimation of the noisy time-dependent processes by maximizing negentropy of innovation when the noise covariance matrix is known. Computer simulations show that the fixed-point algorithm achieves better separation of the noisy mixed signals and noisy mixed images which are difficult to be separated by the basic independent component analysis algorithms, and comparison results verify the fixed-point algorithm converges faster than the existing gradient algorithm and, it is more simple to implement due to it does not need any learning rate.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127428163","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}

The dynamic, heterogeneous and autonomous characteristics of grid make the scheduling approach a complex optimization problem.

Unfortunately, their results have not been satisfied at all yet. In this paper, an improved shuffled frog leaping algorithm is proposed to solve the task scheduling in grid environment, and the simulation experiment results show that the new gird task scheduling algorithm is more robust and efficient than the existing algorithms.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123537370","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}

On the other hand, Broyden-Fletcher-Goldfarb-Shanno (BFGS) -algorithm-based BPNN was also used to compare its prediction performance with that of regularized BPNN. From 1979 to 1998, precipitation and stream flow data in Xitiaoxi watershed for 20 years were collected. All these data were divided into 2 sets: one was the training set (1979-1988), and the other was the testing set (1989-1998). The mean absolute error (MAE), mean square error (MSE) and coefficient of efficiency (CE) were used to evaluate the performance of these two algorithms. The results indicated that regularized BPNN could enhance generalization ability and avoid over fitting effectively, and it outperformed BFGS-algorithm-based BPNN during training and testing stages. From this study, it could be found that regularized BPN is appropriate for rainfall-runoff modeling due to its simple structure and high accuracy.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125819186","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}

Stackelberg game theory is applied to study attack packets sampling problem in network security, and network attack packets sampling model is proposed in this paper. The network security system is regarded as the follower in this game, adjusting the strategies to maximize its benefit function according to the behavior of network attacker. We proved the existence and uniqueness of Stackelberg equilibrium in this game model. Packets sampling algorithm PSA-SM and its equivalent algorithm SPSA were designed based on linear programming. Attack packets injecting algorithm IPIA-GT is also designed. The experiment results showed that network security system can use SPSA to increase the sampling probability of attack packets, and network attacker can also use IPIA-GT to decrease the sampling probability of attack packets. When both of them used optimal strategies, the game got its equilibrium.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125992532","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}

Load transfer between nodes may be done between two or more long-distance nodes. This will delay transfer time, waste some bandwidth resource, result in node failure and network bottleneck. This paper aims to build a controllable, operable P2P network and furthermore benefit the future mobile Internet. This paper presents a new approach to distribute load to nodes within a certain range by introducing Land Mark Node (LMN). LMN is responsible for load regulation and assignment of node ID. In the paper, we explain the new algorithm and compare it with the previous algorithms involving load balancing. Finally we evaluate the benefits of our approach in the context of the P2P network and IMS core network.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128710238","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}
