&lt;p&gt;Due to their rapid spread, computer worms perform harmful tasks in networks, posing a security risk; however, existing worm detection algorithms continue struggle achieve good performance and the reasons for that are: First, large amount of irrelevant data affects classification accuracy. Second, individual classifiers do not detect all types effectively. Third, many systems are based ...

This paper proposes a multi-population χ test method for informative gene selection of a tumor from microarray data based on the statistical multi-population χ test with the sample data being grouped evenly. To test the effectiveness of the multi-population χ test method, we use the support vector machine (SVM) to construct a tumor diagnosis system (i.e., a binary classifier) based on the ident...
