It stores all training patterns and searches to find k nearest neighbors of the given test pattern. Some fundamental improvements to k-NNC are (i) weighted k-nearest neighbor classifier (wk-NNC) where a weight to each of the neighbors is given and is used in the classification, (ii) to use a bootstrapped training set instead of the given training set, etc. Hamamoto et. al. [1] has given a bootstrapping method, where a training pattern is replaced by a weighted mean of a few of its neighbors from its own class of training patterns. It is shown to improve the classification accuracy in most of the cases. The time to create the bootstrapped set is O(n2) where n is the number of training patterns. This paper presents a novel improvement to the k-NNC called k-Nearest Neighbor Mean Classifier (k-NNMC). k-NNMC finds k nearest neighbors for each class of training patterns separately, and finds means for each of these k neighbors (class-wise). Classification is done according to the nearest mean pattern. It is shown experimentally using several standard data-sets that the proposed classifier shows better classification accuracy over k-NNC, wk-NNC and k-NNC using Hamamoto's bootstrapped training set. Further, the proposed method does not have a design phase as the Hamamoto's method, and this is suitable for parallel implementations which can be coupled with any indexing and space reduction methods easily. It is a suitable method to be used in data mining applications.","PeriodicalId":394515,"journal":{"name":"2011 IEEE Recent Advances in Intelligent Computational Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108299","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}

When fault occurs, in case of non-automated and fully automated systems the restoration takes place in single stage whereas in partially automated systems it will be in two- stages. In a two- stage restoration strategy, a first stage quickly restores a limited set of customers using automated switches and at a later stage some other customers are restored by using manual switches. Feeder automation requires a considerable expenditure and therefore at present many utilities are looking for partial automation of feeders which require the concept of two- stage restoration. In the conventional SCADA system, the control decision is taken manually on the basis of experience and the available real time data. It is then executed through the man machine interface. On the other hand, computer based control decisions are taken in the DA system and these control decisions are executed in either automatic mode or in semi-automatic mode through human intervention The reliability indices of RBTS BUS-2 are evaluated for different six cases and the results are compared","PeriodicalId":394515,"journal":{"name":"2011 IEEE Recent Advances in Intelligent Computational Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130406979","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}
