Objective: Medical data mining is a research hotspot. But medical data often contains missing values, which brings difficulties to the medical data analysis. This work evaluates the performance of several imputation methods. Methods: In this paper, we first simulate the missing data set by completely deleting some data from the complete data set, and use the Euclidean distance KNN, the correlation...
A web service security analysis model based on program slicing is proposed, which can be used to find existence of critical information disclosure vulnerabilities and proliferation of such vulnerabilities in a web service net, and eventually improve protection of critical information. Web service protocol is analyzed to obtain external service interfaces; source code is sliced to obtain interface...
An improved algorithm of epipolar line rectification for stereo pairs, which combines Seitz Method with Francesco Method, is proposed. Firstly, the fundamental matrix is calculated using the improved eight-point algorithm (or other improved methods such as weighted normalization algorithm) and then as an input for Seitz Method to get the projective transformation matrices. Finally, these matrices...
The rapid growth of the electronic market and the shift of the global semiconductor manufacturing to Asia have propelled an unprecedented massive expansion of semiconductor industry in China. This development is actively supported by the Chinese government to make the national microelectronics industry more independent, competitive and capable of pulling the development of other high-tech industries,...
