Cognitive Science | Seminar in Cognitive Science
Q700 | 1014 | Hofstadter

Topic: The FARG Models of Analogy and Creativity.  Over a period of
some twenty years, I have worked with graduate students and other
visitors to the Fluid Analogies Research Group in developing models of
cognition, which have then been implemented as computer programs and
tried out.  All of our work has been founded on the premise that
perception of similarity--in other words, analogy-making--is a process
that spans all of thinking, from the simplest to the grandest, and is
therefore the key to understanding the mind.
The seminar will cover several different FARG models, including Jumbo,
Copycat, Metacat, Tabletop, and Letter Spirit, and will also discuss
some alternative approaches, contrasting their premises and results
with our own.  We will also discuss some related issues, including the
mechanisms underlying error-making, the mental process sometimes
called 'frame blending', and the tricky issues of 'meaning'
and 'symbols' in the context of computer models.
