Diagrammatic Methods for Deriving and Relating Temporal Neural Network Algorithms
We present an alternative approach based on a set of simple block diagram manipulation rules. The approach provides a common framework to derive popular algorithms including backpropagation and backpropagation-through-time, without…

Using Differential Constraints to Reconstruct Complex Surfaces from Stereo
Stereo reconstruction algorithms often fail to properly deal with complex surfaces, because there is not enough image information. We propose to guide the reconstruction process using a priori information about…

A Collaborative Environment for Authoring Large Knowledge Bases
Collaborative knowledge base (KB) authoring environments are critical for the construction of high-performance KBs. In this paper, we present an environment that satisfies many of these goals.

A chemical assessment and HPLC assay validation of bulk paromomycin sulfate
This paper describes the compositional analyses of four paromomycin sulfate samples and features a validated HPLC assay method that relies on the fluorescence detection of isoindole derivatives of paromomycin, formed…

The complete genome sequence of the gastric pathogen Helicobacter pylori
Sequence analysis indicates that H. pylori has well-developed systems for motility, for scavenging iron, and for DNA restriction and modification.

Self Calibration of a moving camera from point correspondences and fundamental matrices
We address the problem of estimating three dimensional motion, and structure from motion with an uncalibrated moving camera.

Color in computer vision: recent progress
This chapter introduces the basic principles underlying the physics and perception of color and reviews the state-of-the-art in color vision algorithms.

Exploiting Enterprise Models for the Automatic Distribution of Corporate Information
This paper introduces a new method of distributing information automatically, based on enterprise models—representations of the pertinent aspects of an organization’s structure and operation.
-
Knowledge Intensive Query Processing
The heart of the system is a knowledge base (KB) and a collection of reasoning methods. The KB is being constructed by a combination of manual and semiautomatic methods. The…

Using grammatical inference to improve precision in information extraction
The field of information extraction (IE) is concerned with applying natural language processing (NLP) and information retrieval (IR) techniques to the automatic extraction of essential details from text documents. We…
