Unstable angina (UA) is now a severe burden on society and family in both industrialized and developing countries, but the traditional related factors can not explain the whole situations. The effect of treatment is very limited. Determination of treatment based on the symptoms and signs in Traditional Chinese Medicine (TCM) have certain curative effect. But the objective of the syndrome diagnose...
Although the conventional performance indexes, such as accuracy, are commonly used in classifier selection or evaluation, information-based criteria, such as mutual information, are becoming popular in feature/model selections. In this work, we analyze the classifier learning model with the maximization normalized mutual information (NI) criterion, which is novel and well defined in a compact range...
In this paper, we apply particle swarm optimization (PSO) to solve feature subset selection problems. The proposed PSO algorithm is combined with nearest neighbor classifiers. The algorithm is applied to classify credit risk using benchmark data sets from UCI databases. The experimental results presented in the paper demonstrate that the application of our proposed method lets to achieve better results...
Linear feature can provide more information than point feature and can be extracted and described conveniently compared with the planar structure in the aerial images, a new straight line extraction method for steroimage feature matching is proposed, mainly for the man-made objects. The fusion and the filtering strategies are designed for the linear features extracted from the aerial images, and then...
