Understanding user state and preferences for robust spoken dialog systems and location-aware assistive technology
… and utterance confidence models. With a user simulator, the SDS-POMDP reward function parameters were optimized, and the SDS-POMDP is shown to out-perform simpler threshold-based dialog strategies. These simulations were validated in experiments with human participants, with the SDS-POMDP …

Deep Emotion Analysis of Personal Narratives
… of the trigger events that may have led to a user state. This type of analysis is still in its infancy. In this work, we introduce the concept of Emotion Carriers (EC) as the speech or text segments that may include persons, objects, events, or actions that manifest and explain the emotions …

Machine Learning Methods for functional Near Infrared Spectroscopy
<p>Identification of user state is of interest in a wide range of disciplines that fall under the umbrella of human machine interaction. Functional Near Infra-Red Spectroscopy (fNIRS) device is a relatively new device that enables inference of brain activity through non-invasively pulsing infra-red …

Information Theoretic Limits of State-dependent Networks
… the information theoretic limits of two types of state-dependent models in this dissertation. These models capture a wide range of wireless communication scenarios where there are interference cognition among transmitters. Hence, information theoretic studies of these models provide useful …
