Intervention Participants were allocated to 1 of three 30 minute exposure conditions: GTR (n=13); SBU (n=17); and exposure alone (n=12). Exposure consisted of 2 BATs: a claustrophobia chamber (BAT 1) and a tall filing cabinet (BAT 2). All participants were told that claustrophobia is driven by concerns about lack of fresh air or being trapped. The GTR group was told of the efficacy of eliminati...

Wavelet, a powerful tool for signal processing, can be used to approximate the target function. For enhancing the sparse property of wavelet approximation, a new algorithm was proposed by using wavelet kernel Support Vector Machines (SVM), which can converge to minimum error with better sparsity. Here, wavelet functions would be firstly used to construct the admitted kernel for SVM according to...

Data Mining has great scope in the field of medicine. In this article we introduced one new fuzzy approach for prediction of hepatitis disease. Many researchers have proposed the use of K-nearest neighbor (KNN) for diabetes disease prediction. Some have proposed a different approach by using K-means clustering for reprocessing and then using KNN for classification. In our approach Naive Bayes c...
