Plato laid the foundation of what is now known
as fuzzy logic indicating that there was a third
region beyond true and false. It was Jan
Lukasiewicz who first proposed a systematic
alternative to the bi- valued logic of Aristotle
and described the 3-valued logic, with the third
value being possible. Lotfi Zadeh, in his
theory of fuzzy logic, proposed making the
membership function operate over the range of
real numbers 0,1. He proposed new operations
for the calculus of logic and showed that fuzzy
logic was a generalization of classical
logic. Lotfi Zadeh with John R. Ragazzini,
developed the z- transform method in discrete
time signal processing and analysis, which is now
standard in digital signal processing, digital
control, and other discrete- time systems used In
industry and research. Professor Zadehs latest
work includes computing with words and
perceptions which he will discuss at his BCIG
lecture entitled
Thursday, February 8, 2007 300 to 430 p.m. at
the National Institutes of Health Clinical
Center (Building 10) Medical Board Room (Room
2C116) This lecture is sponsored by the NIH
