چکیده

In this paper, we consider the role that domaindependent control knowledge plays in problem solving systems. Ginsberg and Geddis (Ginsberg & Geddis 1991) h ave claimed that domaindependent control information has no place in declarative systems; instead, they say, such information should be derived from declarative facts about the domain plus domain-independent principles. We dispute their conclusion, arguing that it is impractical to generate control knowledge solely on the basis of logical derivations. We propose that simplifying abstractions are crucial for deriving control knowledge, and, as a result, empirical utility evaluation of the resulting rules will frequently be necessary to validate the utility of derived control knowledge. We ihustrate our arguments with examples from two implemented systems.

Constraint-Based Generalization: Learning Game-Playing Plans From Single Examples

Constraint-based Generalization is a technique for deducing generalizations from a single example. We show how this technique can be used for learning tactical combinations in games and discuss an implementation which learns forced wins in tic-tat-toe, go-moku, and chess.’

Selective Sampling with Co-Testing: Preliminary Results

We present a novel approach to selective sampling, cotesting, which can be applied to problems with redundant views (i.e., problems with multiple disjoint sets of attributes that can be used for learning). The main idea behind co-testing consists of selecting the queries among the unlabeled examples on which the existing
