Data base Adaptive Concept Management control formation systems systems systems alter alter alter assertions parameters structures Figure 1. A "learning system" is an adaptive system that responds acceptably within some time interval following a change in its environment, and a "self-repairing system" is one that responds acceptably within some time interval following a change in its internal structure. This approach was designed to utilize the existing arsenal of control techniques requiring exact specification of the plant. Two broad techniques exist for establishment of convergent control parameter adaptation schemes: search methods and stability analysis.


Models of learning systems

Classics

"The terms adaptation, learning, concept-formation, induction, self-organization, and self-repair have all been used in the context of learning system (LS) research. The research has been conducted within many different scientific communities, however, and these terms have come to have a variety of meanings. It is therefore often difficult to recognize that problems which are described differently may in fact be identical. Learning system models as well are often tuned to the require- ments of a particular discipline and are not suitable for application in related disciplines."In Encyclopedia of Computer Science and Technology, Vol. 11.

On generality and problem solving: a case study using the DENDRAL program

Classics

"Heuristic DENDRAL is a computer program written to solve problems of inductive inference in organic chemistry. This paper will use the design of Heuristic DENDRAL and its performance on different problems for a discussion of the following topics: 1. the design for generality; 2. the performance problems attendant upon too much generality; 3. the coupling of expertise to the general problem solving processes; 4. the symbiotic relationship between generality and expertness, and the implications of this symbiosis for the study and design of problem solving systems. We conclude the paper with a view of the design for a general problem solver that is a variant of the "big switch" theory of generality."See also: Stanford University Report (ACM Citation)In Meltzer, B. and Michie, D.
