Robust Text-Independent Speaker Identification over Telephone Channels
This paper addresses the issue of closed-set text-independent speaker identifcation from samples of speech recorded over the telephone. It focuses on the effects of acoustic mismatches between training and testing…

Finding Consensus Among Words: Lattice-based Word Error Minimization
We describe a new algorithm for finding the hypothesis in a recognition lattice that is expected to minimize the word error rate (WER). Our approach thus overcomes the mismatch between…

At the Boundary of Workflow and AI
This paper describes how techniques from the AI community, specifically reactive control, planning, and scheduling, could be leveraged to develop powerful, next-generation adaptive workflow engines that provide many of the…

Task-based Information Management
We are constructing a system, called the Task-based Information Distribution Environment (TIDE), that delivers information to participants in a dynamic collaboration by evaluating the relevance of incoming and newly generated…

Reconfigurable Elements for a Video Pipeline Processor
This paper describes a family of reconfigurable processing elements (RPEs) used to support video processing for the Sarnoff Vision Front End 200 (VFE-200) vision system.

Construct Validation Of Mathematics Achievement: Evidence From Interview Procedures
This study investigated the validity of measures derived from a large-scale multiple-choice achievement test in mathematics, using evidence from introspective think-aloud protocols of students as they attempted test items.

The Probability Inquiry Environment: A Collaborative, Inquiry-Based Simulation Environment
We report on the Probability Inquiry Environment (PIE), which facilitates the development of probabilistic reasoning by making available collaborative inquiry activities and student-controlled simulations.
