Fast Error-Free Algorithms for Polynomial Matrix Computations
(1990)
Polynomial matrices over fields and rings provide a unifying framework for many control system design problems. These include dynamic compensator design, infinite dimensional systems, controllers for nonlinear systems, and ...
Convergence of a Neural Network Classifier
(1990)
Kohonen's Learning Vector Quantization (LVQ) is a neural network architecture that performs nonparametric classification. It classifies observations by comparing them to k templates called Voronoi vectors. The locations ...
An Algebraic Approach to Feature Interactions
(1990)
Planning the manufacture of machined parts requires a great deal of geometric reasoning. One of the key steps in this task is the derivation of machinable features from a solid model of the part. Regardless of the approach ...
Dynamic Range, Stability, and Fault-tolerant Capability of Finite-precision RLS Systolic Array Based on Givens Rotations
(1990)
The QRD RLS algorithm is generally recognized as having good numerical properties under finite-precision implementation. Also, it is very suitable for VLSI implementation since it can be easily mapped onto a systolic array. ...
Knowledge Strata Reactive Planning with a Multi-level Architecture
(1990)
This report demonstrates the use of "multi-level" or "layered" knowledge representation in Artificial Intelligence planning systems. Although multi-level representation schemes have been in use since the earliest days of ...
On Image Deconvolution Using Multiple Sensors
(1990)
We consider the two dimensional Analytic Bezout Equation (ABE) and investigate the properties of a particular solution, based on-certain conditions imposed on the convolution kernels. The results permit the reconstruction ...
Planning in Uncertain, Unpredictable or Changing Environments
(1990)
This report is a compendium of the extended abstracts submitted by participants at the 1990 AAAI Spring Symposium entitled Planning in Uncertain, Unpredictable or Changing environments. The papers concentrate on extending ...
Adaptive PID Control of Nonlinear Systems
(1990)
Adaptive proportional-integral-derivative (PID) controllers are used to control model-following nonlinear systems with second order deminant dynamics. An Adaptive PID-based controller is designed which drives the difference ...
Nonparametric Classification Using Learning Vector Quantization
(1990)
In this thesis we study several properties of Learning Vector Quantization. LVQ is a nonparametric detection scheme proposed in the neural network community by Kohonen. We examine it in detail, both theoretically and ...
Exploiting Limited Interactions in Plan Optimization
(1990)
Past Planning systems have generally focused on structures capable of working in all domains (domain-independent planning) or on specific heuristics for a particular applied domain (domain-dependent planning). An alternate ...
