We propose MC+, a fast, continuous, nearly unbiased and accu-
rate method of penalized variable selection in high-dimensional linear
regression. The LASSO is fast and continuous, but biased. The bia...
Space Alternating Penalized Kullback Proximal Point Algorithms for Maximing Likelihood with Nondifferentiable Penalty

The EM algorithm is a widely used methodology for penalized likelihood
estimation. Provable monotonicity and convergence are the hallmarks
of the EM algorithm and these properties are well establish...

We consider a Make-to-Order manufacturing system which can be formulated as an
open queueing network composed of some GI/G/1 queueing systems. In Make-to-Order
manufacturing systems, it is important...
