Reasearch and Teaching Interests

چکیده
My primary research interest is in statistical pattern recognition in general, and speech recognition in general; more specifically, I am especially interested in the emerging subfield of distant speech recognition (DSR), wherein it cannot be assumed that the microphone used for speech capture is directly adjacent to the speaker’s mouth; rather, the microphone might be located several meters away from the mouth. This topic is of interest to me, because solving it requires the solution of several problems not encountered in conventional speech recognition, including dealing with the effects of noise, reverberation, and competing speech. The DSR problem is also necessarily interdisciplinary, and shares elements with statistical pattern recognition, digital signal processing, finite-state automata theory, and natural language processing. My first exposure to DSR came while I worked at BBN Technologies in Cambridge, MA. From 1993 to 1997. My initial work involved implmementing algorithms for unsupervised speaker adaptation, whereby the characteristics of a given speaker’s voice are learned, typically in an unsupervised fashion. I also developed techniques for applying speaker adaptation techniques during parameter estimation for hidden Markov models. In the Fall of 1997, I entered the graduate program in the Johns Hopkins University at the Center for Language and Speech Processing; my advisor was Fred Jelinek. At JHU, I continued to work primarily on speaker adaptation algorithms, for which I was awarded a Ph.D. degree in April, 2000. From January, 2000 I took a job as a postdoctoral researcher at the University of Karlsruhe in Karlsruhe, Germany. In 2002 I attended the ICASSP conference in Orlando, FL and bought the book Optimum Array Processing by Harry Van Trees, which had only recently been published. Although well over one thousand pages in length, the word “microphone”—to my knowledge—does not appear even a single time in that work. Nonetheless, Optimum Array Processing, along with a compilation of research papers published earlier, inspired me to begin working on applying microphone arrays to speech recognition. To-

User Interests: Definition, Vocabulary, and Utilization in Unifying Search and Reasoning
Consistent description and representation method of user interests are required for personalized Web applications. In this paper, we provide a formal definition and the “e-foaf:interest” vocabulary for describing user interests based on RDF/OWL and the FOAF vocabulary. As an application, under the framework of unifying search and reasoning (ReaSearch), we proposed interests-based unification of...
متن کامل[Neuroanatomical, genetic and neurochemical aspects of infantile autism].
Infantile autism is a neurodevelopmental disorder characterized by impairments in communication, reciprocal social interaction and restricted repetitive behaviors or interests. Although the cause of these disorders is not yet known, studies strongly suggest a genetic basis with a complex mode of inheritance. The etiopathogenetic processes of autism are extremely complex, which is reflected in t...

The IGPL community and the Editorial Board deeply regrets the untimely death of Professor Jon Barwise on Sunday March 5th of this year. His departure is a great loss, not only to his family and friends and the international logic community, but also to the historical evolutionary development of logic itself. Professor Barwise’s contribution in the areas of pure and applied logic, his active par...
متن کاملJean Gourd Statement of Research
I believe that research and teaching collectively support one another. Research strengthens teaching; teaching sustains research. As a result, a lot of what drives my research is not only based on my personal interests within the field of computer science, but is also influenced by what I teach and, perhaps more specifically, the feedback that I receive from the students that I teach. I find th...
متن کاملA DFT Investigation on The Reaction of tetrazolo [1,5-b][1,2,4]triazine with 1,5-diaminotetrazole and glyoxal in Different Temperatures
In this article, synthesis of the explosive synthesis of tetrazolo [1,5-b][1,2,4]triazine from the reaction of 1,5-diaminotetrazole with glyoxal in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the thermodynamic paramet...
