         MACHINE LEARNING: UNIFYING PRINCIPLES AND RECENT PROGRESS

Machine  learning,  a field concerned with developing computational theories of
learning and constructing learning machines, is now  one  of  the  most  active
research  areas  in  artificial  intelligence.    An  inference-based theory of
learning will be presented that unifies the basic learning strategies.  Special
attention  will  be  given  to  inductive  learning  strategies,  which include
learning from examples and learning from observations and discovery.

We will show that inductive learning can be reviewed  as  a  goal-oriented  and
resource-constrained  inference process.  This process draws upon the learner's
background knowledge, and involves a novel  type  of  inference  rules,  called
inductive  inference rules.  In contrast with truth-preserving deductive rules,
inductive rules are falsity-preserving.

Several projects conducted at our AI Laboratory at  Illinois  will  be  briefly
reviewed, and illustrated by examples from implemented programs.
