Fusion of parametric and non-parametric approaches to noise-robust ASR
In this paper we present a principled method for the fusion of independent estimates of the state likelihood in a Dynamic Bayesian Network (DBN) by means of the Virtual Evidence option for improving speech recognition in the AURORA-2 task. A first estimate is derived from a conventional parametric Gaussian Mixture Model; a second estimate is obtained from a non-parametric Sparse Classification ...

The present study is the efficiency of Iranian industrial universities using non-parametric methods of data envelopment analysis and random border analysis parameter for input variables (number of incoming students, number of faculty members, number of staff and budget) and output (specific income, Has evaluated the number of students studying, the number of graduates and conference papers) and...
متن کاملParametric and non-parametric approaches to price and tax reform
In many public policy problems, we need to estimate the way in which policy changes affect people’s behavior. In the analysis of tax and subsidy reform, which is the topic of this paper, we need to know how tax-induced price changes affect the amounts that people buy of the taxed goods. We present various economic and statistical approaches to obtaining the estimates that are required. We consi...
متن کاملSurvival analysis of breast cancer patients with different chronic diseases through parametric and semi-parametric approaches
Introduction: There is a lack of information on the extent of dependency between chronic diseases and the survival rate of breast cancer. Until date, none of the models proposed has determined the impact of chronic diseases on breast cancer survival. This study, therefore, aimed to investigate the impacts of chronic diseases such as diabetes, blood pressure, and endocrine di...
