this research with explaining of concept of reason and distending with knowledge talks about ethical complementarity of human and relation between that concept and growth of reason with emphasis on ghorar-al-hekam book of imam ali. in this article, we will receive to depth relation between reason and ethic on imam ali’s speeches and ethic without reason isn’t complete and reason without ethic c...

Most HMM-based speech recognition systems use Gaussian mixtures as observation probability density functions. An important goal in all such systems is to improve parsimony. One method is to adjust the type of covariance matrices used. In this work, factored sparse inverse covariance matrices are introduced. Based on U DU factorization, the inverse covariance matrix can be represented using line...

A new form of covariance modelling for Gaussian mixture models and hidden Markov models is presented. This is an extension to an efficient form of covariance modelling used in speech recognition, semi-tied covariance matrices. In the standard form of semi-tied covariance matrices the covariance matrix is decomposed into a highly shared decorrelating transform and a component-specific diagonal c...
