Pablo D. Slemenson“Lógica de lo preconciente”In a paper entitled, Toward a Theory of Fuzzy Information Granulation and itsCentrality in Human Reasoning and Fuzzy Logic (1997), he initiated a new approach tofuzzy logic which links fuzzy logic to granular computing. The theory described in thispaper is likely to have a major impact on fuzzy logic and its applications.In a paper entitled, From Computing with Numbers to Computing with Words -- FromManipulation of Measurements to Manipulation of Perceptions (1999), he initiated acomputational theory of perceptions based on computing with words. This new theorymay well become one of his most important contributions, with wide-rangingapplications in many fields of science and engineering.Lotfi Zadeh became Professor Emeritus in 1991 but remained active in teaching,research and professional service. Among his major professional contributions since hisretirement has been the initiation of the Berkeley Initiative in Soft Computing (BISC).BISC has over two thousand members and over one hundred institutional affiliates.Currently, Lotfi Zadeh is serving as a Professor in the Graduate School, UC Berkeley,and Director of BISC.The concept of soft computing -- which was introduced by Lotfi Zadeh in 1991 -- servesto highlight the emergence of computing methodologies in which the accent is onexploiting the tolerance for imprecision and uncertainty to achieve tractability,robustness and low solution cost. At this juncture, the principal constituents of softcomputing are fuzzy logic, neurocomputing, evolutionary computing and probabilisticcomputing, with the later subsuming belief networks, chaotic systems and parts oflearning theory. What is particularly important about soft computing is that it facilitatesthe use of fuzzy logic, neurocomputing, evolutionary computing and probabilisticcomputing in combination, leading to the concept of hybrid intelligent systems. Suchsystems are rapidly growing in importance and visibility.Currently, Lotfi Zadeh's work is focused on the development of the methodology ofcomputing with words and the computational theory of perceptions. The computationaltheory of perceptions may be viewed as a new direction in fuzzy logic.Apendice 310
