9th Annual Conference of the International-Speech-Communication-Association (INTERSPEECH 2008)
作者: Liu, Peng Soong, Frank Microsoft Res Asia Beijing 100080 Peoples R China
In this paper, we reformulate the optimization in discriminative training (DT) of HMMs as an ellipsoid constrained quadratic programming (ECQP) problem, where a second order of the nonlinear space is adopted. We show ... 详细信息

IEEE SIGNAL PROCESSING LETTERS 2009年 第1-3期16卷 149-152页
作者: Liu, Peng Soong, Frank Microsoft Res Asia Beijing 100190 Peoples R China
In this letter, we reformulate the discriminative training (DT) of continuous density hidden Markov models (CDHMMs) as an ellipsoid constrained quadratic programming (ECQP) problem, and we solve it by a line search al... 详细信息
