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…

Object-Centered Surface Reconstruction: Combining Multi-Image Stereo and Shading
We argue that an object-centered representation is most appropriate for this purpose becasue it naturally accomodates multiple sources of data, multiple images (including motion sequences of a rigid object), and…

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…

Knowledge Representation in the Large
We describe the design and implementation of a storage subsystem that submerges a database management system (DBMS) within a knowledge representation system.

Learning In Interactive Environments: Prior Knowledge And New Experience
Educators often focus on the ideas that they want their audience to have. But research has shown that a learner’s prior knowledge often confounds an educator’s best efforts to deliver…

Motion of an uncalibrated stereo rig: self-calibration and metric reconstruction
We address in this paper the problem of self-calibration and metric reconstruction (up to a scale) from one unknown motion of an uncalibrated stereo rig, assuming the coordinates of the…

The Generic Frame Protocol
The Generic Frame Protocol (GFP) is an application program interface for accessing knowledge bases stored in frame knowledge representation systems (FRSs).

A State-Space Striatal Model
This chapter considers the role of the striatum in computing purposeful state changes.

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…
