From: "Daniel S. Weld" <WELD%MIT-OZ@MIT-MC.ARPA> [Forward from the MIT bboard by SASW@MIT-MC.] Wednesday, March 14 4:00pm 8th floor playroom Acquisition of Procedural Knowledge from Examples P. M. Andreae I will describe NODDY - a system that acquires procedures from examples. NODDY is a variation of concept learning in which the concepts to be learned are procedures in the form of simple robot programs. The procedures are acquired by generalising examples obtained by leading a robot through a sequence of steps. Three distinct types of generalisation are involved: structure generalisation (eg. loops and branches), event generalisation (eg. the branching conditions), and function induction. I will also discuss two principles that arise out of, and are illustrated by, NODDY. I claim that these principles have application, not only to procedure acquisition, but also to any system that does partial matching and/or generalisation of any kind.
