Acoustic Adaptation Using Non-Linear Transformations of HMM Parameters
Speech recognition performance degrades significantly when there is a mismatch between testing and training conditions. Linear transformation-based maximum-likelihood (ML) techniques have been proposed recently to tackle this problem. In this…

Segmenting Reactions to Improve the Behavior of a Planning/Reacting Agent
In this paper, we examine the problem of selecting the best set of reactions for an agent to store. In particular, we examine the benefit of including {em intervals} of…

A Maximum-Likelihood Approach to Stochastic Matching for Robust Speech Recognition
We present a maximum-likelihood(ML)stochastic matching approach to decrease the acoustic mismatch between a test utterance and a given set of speech models so as to reduce the recognition performance degradation…

Scatter/Gather Browsing Communicates The Topic Structure Of A Very Large Text Collection
Users are presented with automatically computed summaries of the contents of clusters of similar documents and provided with a method for navigating through these summaries at different levels of granularity.…

Agent Development Tools for the Open Agent Architecture
The ADT provides a variety of mechanisms that support the specification and implementation of individual agents, as well as cooperating communities of agents. This paper discusses a number of general…

EcoCyc: Electronic Encyclopedia of E. coli Genes and Metabolism
The EcoCyc graphical user interface allows scientists to query and explore the EcoCyc database using visualization tools such as genomic-map browsers and automatic layouts of metabolic pathways.

A Procedural Knowledge Approach to Task-Level Control
This paper describes PRSLite, a task-level controller grounded in a procedural knowledge approach to action description.

Noise-resistant Feature Extraction and Model Training for Robust Speech Recognition
We present a novel noise-robust feature extraction algorithm that is a combination of our previously developed minimum mean square error (MMSE) log-energy estimation algorithm and the probabilistic optimum filtering (POF)…

Canonical representations for the geometries of multiple projective views
We present a new unified representation which will be useful when dealing with multiple views in the case of uncalibrated cameras.

Database Links are a Foundation for Interoperability
This article provides an overview of the DB-interoperation problem, and offers several solutions. It discusses how links are used in molecular biology DBs, and describes the potential stumbling blocks when…
