In high-dimensional data analysis, feature selection becomes one means for dimension reduction, which proceeds with parameter estimation. Concerning accuracy of selection and estimation, we study nonconvex constrained and regularized likelihoods in the presence of nuisance parameters. Theoretically, we show that constrained L(0)-likelihood and its computational surrogate are optimal in that the...
in this paper, iron ore sample from the chadormalu was investigated to determine some comminution properties. chadormalu deposit is one of the largest iron ore mine in iran, which is located in yazd province. the representative ore sample contained 57%fe, 0.9%p and 0.17%s. the sample was crushed; afterward, it was ground in various grinding times according to the bond ball mill approach to spec...
in the linear system ax = b the points x are sometimes constrained to lie in a given subspace s of column space of a. drazin inverse for any singular or nonsingular matrix, exist and is unique. in this paper, the singular consistent or inconsistent constrained linear systems are introduced and the effect of drazin inverse in solving such systems is investigated. constrained linear system arise ...
Robust transmission of real-time video over wireless channels is a challenging problem. This is because the bit error rate (BER) in wireless channels is very high and the bit errors could have devastating effects on the video presentation quality. This paper addresses this problem by introducing adaptive quality-of-service (QoS) control for real-time video communication over wireless channels. ...
