Although CPAP is a highly effective therapy, it is not, however, curative, and it must be used regularly to ameliorate OSA symptoms. Thus, the success of the therapy depends on the patient's compliance and proper use of the CPAP machine. The compliance and continuing use of CPAP might be improved by well-timed and well-designed interventions. There are three major types of interventions: mechanical (applying different types of CPAP machines, altering the air pressure), educational/psychological (improving patient's understanding of treatment, communicating with the health providers), and lifestyle (modifying diet and sleep habits). Therefore, a unified model for various types of interventions is critical for the success of the treatment. In this paper, we propose a multi-system model based on a fuzzy logic approach to assess the extent of the mechanical, educational/psychological, and lifestyle interventions. The CPAP- therapy intervention model, called CPAP-INT, has been designed as a component of a larger system for the comprehensive support of OSA treatment.","PeriodicalId":430770,"journal":{"name":"NAFIPS 2008 - 2008 Annual Meeting of the North American Fuzzy Information Processing Society","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131518006","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}

Game-theoretic probability 博弈论的概率

For von Mises, a sequence of 0s and 1s was random if the frequency of 1s converged to one-half on (1) the sequence as a whole and (2) any reasonably chosen subsequence. Convergence on subsequences is needed, he said, to keep a gambler from beating the odds by choosing when to bet. Ville pointed out that more is needed. The gambler can also vary the amount he bets and the side on which he bets. Since 2001, Vladimir and Vovk and I have sought to revive Ville's idea of basing probability on game theory. In this talk, I explain how the game-theoretic approach leads to a new understanding of classical probability and finance and a new method of prediction. I also discuss why Ville's ideas were forgotten by statisticians and philosophers for 60 years. Because he wrote in French? Because he was a prisoner of war? Because of his bohemian lifestyle? Because he spent too much time teaching and consulting to pay for it? Because he was a dilettante? Or was he just too far ahead of his time?","PeriodicalId":430770,"journal":{"name":"NAFIPS 2008 - 2008 Annual Meeting of the North American Fuzzy Information Processing Society","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123040120","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 resulting association rules are then matched against a set of fuzzy concepts. These concepts comprise user-built linguistic propositions that describe the evolution of rules that might be considered interesting. The proposed technique is evaluated on a real-world data set. To present the results, we introduce a modified rule visualization along the way that is an extension of our previous work.","PeriodicalId":430770,"journal":{"name":"NAFIPS 2008 - 2008 Annual Meeting of the North American Fuzzy Information Processing Society","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130100484","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 new algorithm goes beyond previously published MCE based approaches. It has the advantage that it is applicable to general measures, as opposed to only the Sugeno class of measures. In addition, the monotonicity constraints are handled easily with minimal time or storage requirements. This is made by the use of an alternated sampling to avoid favoring maxlike operators or min-like operators. The use of the logistic distribution eliminates the necessity of using desired outputs, and the Laplacian prior regularize the parameters in the fuzzy measures. Results are given on synthetic and real data sets, the latter obtained from a landmine detection problem.","PeriodicalId":430770,"journal":{"name":"NAFIPS 2008 - 2008 Annual Meeting of the North American Fuzzy Information Processing Society","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126709310","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}
