We describe a variant of Quinlan's ID3 algorithm (1986) which is attuned to the situation that every feature's value-set is linearly ordered and finite. We then seek economical training sets, that is, ones which are small in size but result in learned decision trees of high accuracy. Our search focuses on geometric properties of the target concept, such as its extreme points, edges, faces, and surface. We categorize all concepts into three classes, from simplest to most general, and for each class we identify certain training sets, some quite small, others less so, which result in highly accurate learning of the concepts in that class. Some of our results are rigorously provable (but the proofs do not appear here), for other results our evidence is empirical.<<ETX>>","PeriodicalId":119615,"journal":{"name":"Proceedings of SOUTHEASTCON '94","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117297084","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}

However, meeting these responsibilities has become increasingly complex because of the new technical, economical, environmental, political, and social considerations. The effect of these considerations/constraints has increased the uncertainty in the planning process and raised operating and capital costs. Therefore, utilities have sought means to control the rate of peak load, improve the efficiency/utilization of present electric energy systems and to reduce requirements for additional generation, transmission, and distribution investments. These methods form the set of functions known as load management. In this paper, application of the residential load management program of Florida Power and Light (FPL) is discussed. The load management program in South Florida is evaluated from both the utility and customer's perspectives. This includes establishment of a residential load management program, utility cost and benefits of the program, customer acceptance, and system configuration.<<ETX>>","PeriodicalId":119615,"journal":{"name":"Proceedings of SOUTHEASTCON '94","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120956300","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}

Hence algorithms which give improved convergence on upper and lower bounds for the reliability midway through the problem are desirable. This paper introduces a previously unreported idea for partitioning in network reliability algorithms and compares experimental results on convergence rates of the reliability bounds using several strategies. The results indicate that as much as an order of magnitude difference in convergence rates exist between best and worst strategies midway through the problem.<<ETX>>","PeriodicalId":119615,"journal":{"name":"Proceedings of SOUTHEASTCON '94","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117211273","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}
