An understanding of learning -- the process by which a learner
acquires and refines a broad range of knowledge and skills -- is central to
the enterprise of building truly adaptive, flexible, robust, and creative
intelligent systems. Significant theoretical and empirical contributions to
the characterization of learning in computational terms have emerged from
research in a number of disparate research paradigms. The limitations of
individual paradigms and of particular classes of techniques within each
paradigm are beginning to be recognized. Converging lines of evidence from
multiple sources, both theoretical as well as empirical, suggest that
artificial intelligence systems, in order to be able to deal with complex
tasks such as recognizing and describing 3-dimensional objects, or
communicating in natural language, must be able to effectively utilize a
range of learning algorithms operating with an adequate repertoire of
representational structures. This paper draws on a broad range of research
on learning in artificial intelligence, connectionist networks, statistical
and syntactic methods in pattern recognition, and evolutionary models to
identify the similarities and differences among, strengths and limitations of,
and promising areas for cross-fertilization between, the different paradigms.
