Tracking of enriched dialog states for flexible conversational information access
Yinpei Dai, Zhijian Ou, Dawei Ren +1
Dialog state tracking (DST) is a crucial component in a task-oriented dialog system for conversational information access. A common practice in current dialog systems is to define…
Learning neural trans-dimensional random field language models with noise-contrastive estimation
Bin Wang, Zhijian Ou
Trans-dimensional random field language models (TRF LMs) where sentences are modeled as a collection of random fields, have shown close performance with LSTM LMs in speech recognit…
Language modeling with Neural trans-dimensional random fields
Bin Wang, Zhijian Ou
Trans-dimensional random field language models (TRF LMs) have recently been introduced, where sentences are modeled as a collection of random fields. The TRF approach has been show…
Joint Bayesian Gaussian discriminant analysis for speaker verification
Yiyan Wang, Haotian Xu, Zhijian Ou
State-of-the-art i-vector based speaker verification relies on variants of Probabilistic Linear Discriminant Analysis (PLDA) for discriminant analysis. We are mainly motivated by t…
