In this paper, we studied the filter trading rule under a model assumption of Markov switching model (MSM) which has become very popular in financial applications. From our studies, it is found that the filter trading rule may beat the buy-and-hold strategy when the two-regime MSM fit the asset returns well.","PeriodicalId":294223,"journal":{"name":"2013 Ninth International Conference on Computational Intelligence and Security","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128812093","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}

Users of a e-commerce system may have some kind of relationship according to the corresponding application. Such kind of connected users can be viewed as vertices jointed by hyper-edges, and thus formed a hyper graph. Colluders are those clusters in the hyper graph that all of their vertices are closely connected via hyper edges. Thus the task of detecting colluders from common users is converted to be a problem of finding those tightly connected clusters, which can be found by splitting the hyper graph according to modularity defined in this paper. Experiment shows that such modularity attribute of colluder groups are generally of large values while are of little value for common user groups, which demonstrates the effectiveness of our proposed model and algorithm.","PeriodicalId":294223,"journal":{"name":"2013 Ninth International Conference on Computational Intelligence and Security","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116686215","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 accuracy of Shot-Boundary detection directly affects the retrieval system performance. There are many shot boundary detection algorithms, such as pixel-based algorithms and histogram-based algorithms, etc. However, these shot boundary detection algorithms are not good at detecting motion shot. This paper proposes an adaptive shot boundary detection algorithm based on HSV space. Comparing with existing pixel-based algorithms, our algorithm consider the characteristics of two shot transitions and uses different data processing in cut and gradual transition detection. Compared with histogram method, the algorithm using partitioning technology, combined with the relationship between spatial and color information. Experimental results show that the proposed method has stronger anti-interference performance compared with existing algorithms.","PeriodicalId":294223,"journal":{"name":"2013 Ninth International Conference on Computational Intelligence and Security","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116209925","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}

Thus, using phonemes directly translated from their written forms as basic units for acoustic modeling is problematic, as these units lack the ability to capture the complex pronunciation variations occurred in continuous speech. Allophone, a sub-phone unit in phonetics but served as independent phoneme in speech recognition, is considered to have the ability to describe complex pronunciation variations. This paper presents a novel approach called Automatic Allophone Deriving (AAD). In this approach, statistics from Gaussian Mixture Models are used to create measurements for allophone candidates, and decision trees are used to derive allophones. Question set used by the decision tree is also generated automatically, since we assumed no linguistic knowledge would be used in this approach. This paper also adopts long-time features over conventional cepstral features to capture acoustic information over several hundred milliseconds for AAD, as co-articulation effects are unlikely to be limited to a single phoneme. Experiment shows that AAD outperforms previous approaches which derive allophones from linguistic knowledge. Additional experiments use long-time features directly in acoustic modeling. The results show that performance improvement achieved by using the same allophones can be significantly improved by using long-time features, compared with corresponding baselines.","PeriodicalId":294223,"journal":{"name":"2013 Ninth International Conference on Computational Intelligence and Security","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115791759","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 weights of each expert can be obtained by analyzing the similarity of judgment matrixes experts offer, and then we can get the objective and representative polymerization decisive opinions which enhance the reliability of the decision-making results.
