The purpose of the study is to ascertain the key feature subsets of hepatitis b virus (HBV) reactivation and establish classification prognosis models of HBV reactivation for primary liver carcinoma (PLC) patients after precise radiotherapy (RT). Genetic Algorithm (GA) is proposed to extract the key feature subsets of HBV reactivation from the initial feature sets of primary liver carcinoma. Bayes...
Mutual information (MI) is a well accepted similarity measure for image registration. However, MI based registration faces the challenges of high computational complexity, low registration efficiency and high likelihood of being trapped into local optima due to an absence of spatial information. In this paper, we propose a new multiscale registration framework based upon an edge preserving total variation...
A feature extraction method is proposed for discriminating three kinds of Chinese vinegars based on a gas sensor array composed of 13 Taguchi gas sensors (TGS). It employs three-scale wavelet packet analysis to decompose each signal of the sensor array into eight difference frequency bands, and the feature values can be obtained by computing the maximum of relative energy corresponding to each frequency...
