We shall mentioned our initial idea: Zadeh gave an intuitive definition in (Zadeh, 1996) and outline his seminal paper (Zadeh, 1997), where he said “TFIG (which is GrC) • • • • are mathematics in nature.” While we share his view, but took an incremental approach.

One is L2-regularization term and the other is L1-regularization one for tolerance vector. Introducing a concept of clusterwise tolerance, we have proposed tolerant fuzzy c-means clustering from the viewpoint of handling data more flexibly. In tolerant fuzzy c-means clustering, a constraint for tolerance vector which restricts the upper bound of tolerance vector is used. In this paper, regularization terms for tolerance vector are used instead of the constraint. First, the concept of clusterwise tolerance is introduced. Second, optimization problems for tolerant fuzzy c-means clustering with regularization term are formulated. Third, optimal solutions of these optimization problems are derived. Fourth, new clustering algorithms are constructed based on the explicit optimal solutions. Finally, effectiveness of proposed algorithms is verified through numerical examples.","PeriodicalId":388774,"journal":{"name":"2009 IEEE International Conference on Granular Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122964314","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}

Given a database for a set of individuals characterized by both “local” attributes such as age and criminal background, and “relational” information such as communications among a subset of the individuals, with a subset of the individuals labeled as terrorist or normal people, our task is to design a classifier that captures the patterns of terrorists and achieves good accuracy in predicting the labels of the remaining part of the database. In previous work, a hybrid approach was presented that iteratively applies a flat classifier (such as decision trees, fuzzy clustering) augmented with flattened relational attributes for learning and classification. In the current work, our approach is to use random forest as the “flat” classifier in the terrorist detection setting. Random forest is known to have advantage in handling tasks with high dimensionality in input data. This merit of random forest method is very useful for relational learning if the number of “flattened” relational attributes is quite large, which is indeed the case for the terrorist detection task. We report our experiments on a synthetic terrorist database that compare the prediction accuracy of random forest with two other “flat” classifiers, namely, ordinary decision tree and fuzzy clustering. The experimental results show that random forest outperforms both ordinary decision tree and fuzzy clustering. random forest","PeriodicalId":388774,"journal":{"name":"2009 IEEE International Conference on Granular Computing","volume":"36 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125725978","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}

Binding theory and security prerequisites proposition to authentication protocols can simply and efficiently decide security properties when authentication protocols have security weakness for authentication properties.
