This volume contains the papers that were presented at the
Third Workshop onAlgorithmic Learning Theory, held in Tokyo
in October 1992. In addition to 3invited papers, the volume
contains 19 papers accepted for presentation, selected from
29 submitted extended abstracts. The ALT workshops have been
held annually since 1990 and are organized and sponsored by
the Japanese Society for Artificial Intelligence. The main
objective of these workshops is to provide an open forum for
discussions and exchanges of ideasbetween researchers from
various backgrounds in this emerging, interdisciplinary
field of learning theory. The volume is organized into parts
on learning via query, neural networks, inductive inference,
analogical reasoning, and approximate learning.
