Spoken dialogue system has an uncertain parameter during the speech recognition which controls its performance that vary for the different users as well as for the same user during multiple repetitions of even the same dialogue. This paper discusses how recognition errors in the users utterances can be handled by making use of semi-supervised learning techniques over the hidden vector state (HV...

In this project, two improved perceptual quality methods are proposed. One is weighted PSNR (WPSNR). Based on the fact that the human eye will have less sensitivity to modifications in textured areas than in smooth areas, WPSNR uses an additional parameter called the Noise Visibility Function (NVF) that is a texture masking function as a penalization factor. The other method based on Watson HVS...

Polyclonal hyperviscosity syndrome (HVS) is rare and has been reported in various disorders of immune dysregulation and lymphoid hyperplasia. IgG4-Related Disease (IgG4-RD) is an emerging disorder often associated with exuberant hypergammaglobulinemia, and this review of seven cases establishes IgG4-RD as an important cause of polyclonal HVS.

Background Hyperventilation syndrome (HVS) sometimes occurs in patients under stressful conditions and may provoke severe complications such as myocardial infarction and death. The authors report a case of HVS following general anesthesia, where a continuous intravenous infusion of dexmedetomidine was effective for HVS. Case presentation A 23-year-old male patient with recurrent tongue cancer...

EEG and single-unit techniques have been used to study the EEG correlates of cellular firing in the neocortex, n. reticularis (RT) and "specific" thalamic nuclei, and the cholinergic forebrain area (nucleus basalis, NB). Neuronal firing was related to the ongoing behavior of the rat. In addition, using a 16-channel neocortical recording/mapping system, we studied the effects of ibotenic acid le...

Cognitive impairment is common in patients with schizophrenia, and even those with relatively preserved function perform worse than healthy volunteers (HVs) on attentional tasks. This is consistent with the hypothesis that connectivity - in the frontoparietal network (FPN) activated during attention - is disrupted in schizophrenia. We examined attentional effects on connectivity in the FPN, in ...
