The role of intelligent systems in the national information infrastructure
AI techniques can play a central role in the development of a useful and usable NII by (1) enabling the construction of human-computer interface systems that are goal-oriented, cooperative, and…

A Robust Technique for Matching Two Uncalibrated Images Through the Recovery of the Unknown Epipolar Geometry
This paper proposes a robust approach to image matching by exploiting the only available geometric constraint, namely, the epipolar constraint.

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.

A Comparative Study of Speaker Adaptation Techniques
In this paper, we study various ML-based techniques and compare experimental results on data sets with recordings from nonnative and native speakers of American English. In feature-space techniques, we hypothesize…

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…

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).

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…

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