In order to solve these problems, a subband blind adaptive array processing algorithm is proposed in this paper, which applies the space-time interference suppression technology to Direct Sequence Spread Spectrum (DSSS) system. For one thing, compared to the pure space-domain processing, Sub-band adaptive array (SBAA) greatly increases the freedoms of degree. For another, it also simplifies algorithm complexity relative to Tapped-delay-line adaptive array (TDLAA) structure of traditional STAP. The proposed sub-band blind adaptive array algorithm can provide higher convergence speed and better convergence accuracy with low algorithm complexity. Furthermore, the novel algorithm doesn't need training sequences, increasing the ability of tracing signal changes in real time. Simulation results show that the novel space-time interference suppression scheme exhibits a better anti-jamming performance.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"397 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126756832","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}

Traditional image classification methods generally utilize Support Vector Machines (SVM) as image classifier. However, there are several drawbacks of using SVM, such as the high computational cost and large number of parameters to be optimized. In this paper we propose an Extreme Learning Machine (ELM) based Multi-modality Classifier Combination Framework (MCCF) to improve the accuracy of image classification. In this framework: (i) three ELM classifiers are trained by exploring three kinds of visual features respectively, (ii) a probability based fusion method is then proposed to combine the prediction results of each ELM classifier. Experiments on the widely used TRECVID datasets demonstrate that our approach can effectively improve the accuracy of image classification and achieve performance at extremely high speed.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116695417","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}

However, using a single biometric has several problems. In order to alleviate these problems, multi-modal biometric systems are proposed by combining various biometric modalities to improve the robustness of person authentication. A typical application is to combine both audio and face for multimodal person recognition, since either face or voice is among the most natural biometrics that people use to identify each other. In this paper, a novel approach called multi-feature subspace analysis (MFSA) is proposed for audio-video based biometric person recognition. In the MFSA framework, each face sequence or utterance is represented with a fix-length feature vector, and then subspace analysis method is performed on a collection of random subspaces to construct an ensemble of classifiers for robust recognition. Experiments on the XM2VTSDB corpus sufficiently validate the feasibility and effectiveness of our new approach.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116739591","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}

Since its introduction, the parameter tuning of PSO has always been a hot topic. As a robust design method, the Taguchi method is known as a good tool in designing parameters. Thus the Taguchi method is adopted to analyze the effect of inertia weight, acceleration coefficients, population size, fitness evaluations, and population topology on PSO, and to identify the best settings of them for different optimization problems. The results of benchmark functions show that the optimum parameter settings depend on the benchmarks, and all the functions obtain their optimum solutions after parameter tuning. Good result are also achieved when dealing with the optimization design of a Halbach permanent magnet motor, which indicates that the PSO with best parameter settings identified by the Taguchi method is more suitable to such actual engineering problem.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127020560","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}

How to predict protein' PTMs types is an important and challenging problem. Most of the existing approaches can only be used to recognize single-label PTMs type. By introducing the multi-labeled K-Nearest-Neighbor algorithm, a new predictor has been proposed which can be used to dispose of the proteins containing both single and multi-label PTMs type. As a result that the 10-fold crosses validation was implemented on a benchmark data set of proteins which were divided into the following 4 types: (1) methylation, (2) nitrosylation, (3) acetylation, (4) phosphorylation, where many proteins belong to two or more types.

Because during the ligation of the DNA strands, the bio-reaction's character is to combine all the possible single DNA strands into the shortest double DNA strand. We propose a DNA model with the coding strategy and DNA computing algorithm for the hierarchical clustering problem. we use this algorithm to solve the real problem - the retailer's region partition problem.

However, as the interference to licensed spectrum owners needs to be strictly controlled, CR enabled users (CRs) should vacate the using channel immediately on detecting licensed users activity and the end to end performance may be seriously degraded. In this paper, we propose a robust routing scheme for cognitive radio ad hoc networks that can accommodate to the spectrum availability variation and keep stable to guarantee the end to end performance of CRs. The path stability is modeled considering both available channel numbers and channel characteristic along the path. The paths beyond a robust threshold are regarded to be feasible and the one with maximal throughput is chosen for transmission. Simulation results show that the proposed scheme performs much better than other existing protocols in terms of route throughput and stability maintenance.","PeriodicalId":306383,"journal":{"name":"2014 4th IEEE International Conference on Information Science and Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124755323","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}
