A large part of the factors which influence the success of a data mining problem reside in the quality of the data used. Feature selection represents one of the tools which can refine a dataset before presenting it to a learning scheme. This paper analyzes a wrapper approach for feature selection, with the purpose of boosting the classification accuracy. A wrapper is viewed as a 3-tuple consisting of a generation procedure, an evaluation function and a validation procedure. Experimental evaluations have been performed for several combinations of the three components. The results have shown that feature selection improves the classification accuracy and speeds up the training process. Moreover, two robust combinations are proposed: one that constantly achieves highest accuracy, and one which significantly boosts the initial accuracy of the inducer.","PeriodicalId":169031,"journal":{"name":"2008 4th International Conference on Intelligent Computer Communication and Processing","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132583795","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}

These methods try to exploit the information provided by the large and easily gathered unlabeled data besides the labeled training set. Analogously, many semi-supervised kernels appeared which determine similarity in feature space considering also the unlabeled data points. In this paper we propose a novel kernel construction algorithm for supervised and semi-supervised learning, which actually constitutes a general frame of semi-supervised kernel construction. The technique is based on the cluster assumption: we cluster the labeled and unlabeled data by an agglomerative clustering technique, and then we use the linkage distances induced by the clustering hierarchy to construct our kernel. The hierarchical cluster kernel is then compared to other existing techniques and evaluated on synthetic and real data sets.","PeriodicalId":169031,"journal":{"name":"2008 4th International Conference on Intelligent Computer Communication and Processing","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133132330","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}

Cryptographic protocols are used to provide security services such as confidentiality, message integrity, authentication, certified E-mail and non-repudiation. Traditionally, security protocols have been designed and verified using informal techniques. However, the absence of formal verification can lead to security errors remaining undetected. Formal verification techniques provide a systematic way of discovering protocol flaws. This paper establishes a freshness flaw in a key-distribution and authentication protocol using an automated logic-based verification engine. The performed verification reveals a freshness flaw in the protocol that allows an intruder to impersonate legitimate principals. The cause of the freshness flaw is discussed and an amended protocol is proposed. Formal verification of the amended protocol provides confidence in the correctness and effectiveness of the proposed modifications.","PeriodicalId":169031,"journal":{"name":"2008 4th International Conference on Intelligent Computer Communication and Processing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115000010","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}

Many Internet sites offers services for human users, but unfortunately some computer programs are designed to abuse these services. To solve this problem, some systems named CAPTCHA (completely automated public Turing test to tell computers and human apart) have been introduced to distinguish between human users and computer programs. CAPTCHA methods are mainly based on the weaknesses of OCR systems while using them is undesirable for human users, especially for disabled people. Therefore some CAPTCHA methods are designed especially for disabled people, but there is no method for peoples with more than one disability.

This paper presents a solution for lane estimation in difficult scenarios based on the particle filtering framework. The solution employs a novel technique for pitch detection based on fusion of two stereovision-based cues, a novel method for particle measurement and weighting using multiple lane delimiting cues extracted by grayscale and stereo data processing, and a novel method for deciding upon the validity of the lane estimation results. The working range of the lane detection algorithm is automatically determined based on vehicle speed and the availability of 3D data points. Initialization samples are used for uniform handling of the road discontinuities, eliminating the need for explicit track initialization.","PeriodicalId":169031,"journal":{"name":"2008 4th International Conference on Intelligent Computer Communication and Processing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128811613","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}
