As traditional microstrip antenna has the disadvantage of narrow bandwidth, a kind of adaptive differential evolution algorithm based on dual population has been put forward, in combination with RWG-SWG hybrid basis function integral equation, to optimize and design a wideband antenna. In the algorithm, one population as a development and another population as a probe are used to increase the diversity...
We consider the high-dimensional discriminant analysis problem. For this problem, different methods have been proposed and justified by establishing exact convergence rates for the classification risk, as well as the $\ell _{2}$ convergence results to the discriminative rule. However, sharp theoretical analysis for the variable selection performance of these procedures have not been established,...
