Classification is an important data mining technique that consists of assigning a data instance to one of the several predefined categories. Various successful methods have been suggested and tested to solve the problem in the binary classification case. However, the multiclass classification has been attempted by only few researchers. The objective of this paper is to investigate various techniques for solving the multiclass classification problem. Three non-evolutionary and one evolutionary algorithm are compared on four datasets. Further, using this analysis, the paper presents the benefits of producing a hybrid classifier by combining evolutionary and non-evolutionary algorithms; specifically, by merging Genetic Programming and Decision Tree.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133271849","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 Distributed generation based on microturbine technology is new and a fast growing business. In this paper the detailed model of a single-shaft MTG system suitable for both grid connected and islanding operation has been presented, which is practically feasible. The developed model allows the bidirectional power flow between grid and MTG system. For the purpose of modeling, a dynamic model for each component in the system, including microturbine, PMSM, m/c side converter controller, line side controller and LCL filter is developed. The results are validated in MATLAB/SIMULINK.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128898505","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 proposed approach involve solving significantly less number of decision variables as compared to some of the other recently reported results. It is shown that in the absence of nonlinearities and uncertainties, our approach can be used for the stability analysis of linear discrete-time state-delayed system. The effectiveness of the proposed results is illustrated with the help of an example.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127509485","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 present day financial self-service has made the currency recognition a key activity of the automated banking process. The process of the currency recognition by some extrinsic feature becomes error prone due the pollution and depreciation suffered by the currency during the transactions. Therefore we propose an Indian currency recognition system based on the intrinsic feature of the currency. In the present work we extracted texture as intrinsic features for currency recognition and evaluated the class discriminating capability of these features for Indian currency.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"406 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123383644","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 emphasis is now shifted from simply retrieving a set of documents to rank them also for a given query in terms of user's need. The researcher's task is not only to retrieve the documents from the corpus but also to rank them in order of their relevance to the user's requirement. To improve the system's performance is now the hot area of research. In this paper, an attempt has been made to put some of most commonly used algorithms in the community.

Interestingly 90% of the time the mail server classifies it perfectly but sometimes it fails due to spammer are getting highly technical. In this paper, we are using novel approach which uses Vector space model with Naïve Bayes to correctly classify mails as spam mail. Naïve Bayes method is used for spam classification but still binding with personalize word vector helps in increasing the accuracy of the system because user receives special type of message only. In this research work, we use vector space model with naïve bayes to classify spam mail. We got nearly 85% of accuracy in spam classification. We have used personalize mail classification option instead of standard global classification because people visiting subjective (i.e. pornographic) sites frequently get spam mail related to that subject (pornography) only and hence personalization shows improved result.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126658104","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}
