Discriminative training of HMM stream exponents for audio-visual speech recognition
We propose the use of discriminative training by means of the generalized probabilistic descent (GPD) algorithm to estimate hidden Markov model (HMM) stream exponents for audio-visual speech recognition. Synchronized audio and visual features are used to respectively train audio-only and visual-only single-stream HMMs of identical topology by maximum likelihood. A two-stream HMM is then obtaine...
متن کاملDiscriminative speaker adaptation using articulatory features
This paper presents an automatic speech recognition system using acoustic models based on both sub-phonetic units and broad, phonological features such as Voiced and Round as output densities in a hidden Markov model framework. The aim of this work is to improve speech recognition performance particularly on conversational speech by using units other than phones as a basis for discrimination be...
متن کاملCombined discriminative training for multi-stream HMM-based audio-visual speech recognition
In this paper we investigate discriminative training of models and feature space for a multi-stream hidden Markov model (HMM) based audio-visual speech recognizer (AVSR). Since the two streams are used together in decoding, we propose to train the parameters of the two streams jointly. This is in contrast to prior work which has considered discriminative training of parameters in each stream in...
متن کاملDiagnosis of OCD Patients Using Drawing Features of Bender Gestalt Shapes
Background: Since psychological tests such as questionnaire or drawing tests are almost qualitative, their results carry a degree of uncertainty and sometimes subjectivity. The deficiency of all drawing tests is that the assessment is carried out after drawing the objects and lots of information such as pen angle, speed, curvature and pressure are missed through the test. In other words, the ps...
متن کاملAn algorithm for determining common weights by concept of membership function
Data envelopment analysis (DEA) is a method to evaluate the relative efficiency of decision making units (DMUs). In this method, the issue has always been to determine a set of weights for each DMU which often caused many problems. Since the DEA models also have the multi-objective linear programming (MOLP) problems nature, a rational relationship can be established between MOLP and DEA problem...
