Transfer of Learning in Soar
Soar exhibits all three types of learning Transfer.
-
Within-Trial Transfer
When chunks are created they are
available for immediate application. Thus, within a single problem
solving session, chunks may be applied as soon as they are learned.
-
Across-Trial Transfer
As chunks are created, system performance over different instances of the
same problem improves. This is another way of saying that Soar moves from
problematic to routine behavior or
that Soar gets better at similar tasks
with practice. In particular, the chunking mechanism
in Soar has been shown to demonstrate results consistent with the
power law of
practice. This transfer is a direct result of chunking's
ability to generalize.
Across-Task Transfer
Soar has also demonstrated across-task transfer: applying knowledge
learned in one domain to another. In one sense, this can be viewed
as a form of
analogical learning. However, the
analogies can be very simple. For instance, if turning a doorknob
results in opening a door then perhaps turning a jar top will result
in opening a jar.
