Connectionist Speaker Normalization and Adaptation
We explore supervised speaker adaptation and normalization in the MLP component of a hybrid hidden Markov model/multilayer perceptron version of SRI's DECIPHER™ speech recognition system. Our approach combines both adaptation…

Training Data Clustering for Improved Speech Recognition
We present an approach to cluster the training data for automatic speech recognition (ASR). A relative entropy based distance metric between training data clusters is defined.

Acoustic Properties of Disfluent Repetitions
Acoustic properties of disfluent repetitions are examined to investigate two proposed functions of repeating. Repeating may serve as a filler while hesitating; alternatively, repeating may function to bridge a gap…

Adapting CLIM Applications for Use on the World Wide Web
We have developed a Web server tool, written in Common Lisp, that allows any existing graphical user interface application written using the Common Lisp Interface Manager (CLIM) to hook easily…

An Efficient Probabilistic Context-Free Parsing Algorithm that Computes Prefix Probabilities
We describe an extension of Earley's parser for stochastic context-free grammars that computes quantities given a stochastic context-free grammar and an input string.

WebWatcher: A Learning Apprentice for the World Wide Web
We describe an information seeking assistant for the world wide web. This agent, called WebWatcher, interactively helps users locate desired information by employing learned knowledge about which hyperlinks are likely…

New results in stereo-based automatic vehicle guidance
Presents new results on vision based longitudinal and lateral vehicle control. The novel feature of this approach is the use of binocular vision.

Planning and Reacting in Uncertain and Dynamic Environments
The CYPRESS system is a domain-independent framework for defining persistent agents with this full range of behavior. It has been used for several demanding applications, including military operations, real-time tracking,…

WebWatcher: Knowledge Navigation in the World Wide Web
We describe a learning apprentice system, called WebWatcher, which both performs the kind of indexing used by Web catalogers like Lycos, and attempts to exploit the two sources of knowledge…
-
An integrated stereo-based approach to automatic vehicle guidance
We integrate two modules consisting of a new, domain-specific, efficient binocular stereo algorithm, and a lane marker detection algorithm, and show that the integration results in a improved performance for…
