Remembering Lotfi Zadeh
Dimitar Filev
Prof. Lotfi Zadeh, one of the titans of systems science, control
theory, and artificial intelligence (AI), invented the concept
of fuzzy sets and created the theory of fuzzy logic, fuzzy
systems, and approximate reasoning. He was the founder of
the broad and long-reaching vision of soft computing as a
profound engineering approach to AI combining the power
of neural networks, fuzzy systems, evolutionary computing,
and machine learning. His interests and contributions
expanded from deciphering the complexity of human
reasoning and natural language to the very pragmatics of
industrial applications of soft computing. Prof. Zadeh was a
remarkable icon of scientific research and engineering, yet
he was very humble, so I will mention with utmost discretion
only some of the accolades that testify to the significance
of his legacy and contributions to science, engineering, and
humanity in general: membership in the National Academy
