Employing Stochastic Constrained Lms Algorithm for Asr Frontend Processing
نویسندگان
چکیده
In scenarios with multiple input single output systems, the stochastic constrained least mean-squares (LMS) algorithm has been proven to be an effective approach. However, when only two input channels are available, it is unclear whether this approach still yields improvements. In this paper, we investigate the stableness and the robustness of the constrained LMS algorithm on “Track 1” of “2 CHiME Challenge” [1] and show that it leads to small yet consistent improvements on all signal-to-noise settings.

Viterbi decoding for latent words language models using gibbs sampling
This paper introduces a new approach that directly uses latent words language models (LWLMs) in automatic speech recognition (ASR). LWLMs are effective against data sparseness because of their soft-decision clustering structure and Bayesian modeling so it can be expected that LWLMs perform robustly in multiple ASR tasks. Unfortunately, implementing a LWLM to ASR is difficult because of its comp...
متن کاملAn Analytical Model for Predicting the Convergence Behavior of the Least Mean Mixed-Norm (LMMN) Algorithm
The Least Mean Mixed-Norm (LMMN) algorithm is a stochastic gradient-based algorithm whose objective is to minimum a combination of the cost functions of the Least Mean Square (LMS) and Least Mean Fourth (LMF) algorithms. This algorithm has inherited many properties and advantages of the LMS and LMF algorithms and mitigated their weaknesses in some ways. The main issue of the LMMN algorithm is t...
متن کاملSplittable stochastic project scheduling with constrained renewable resource
This paper discusses the problem of allocation of constrained renewable resource to splittable activities of a single project. If the activities of stochastic projects can be split, these projects may be completed in shorter time when the available resource is constrained. It is assumed that the resource amount required to accom-plish each activity is a discrete quantity and deterministic. The ...
