"malicious" training patterns

[Gerald Tesauro]

The notion that points close to the decision surface are "malicious"
comes as a surprise to me. From the point of view of extracting good
generalizations from a limited number of training patterns, such
"borderline" training patterns may in fact be the best possible
patterns to use. A benevolent teacher might very well explicitly
design a bunch of border patterns to clearly mark the boundaries
between different conceptual classes.
