ABSTRACT: Achievement of human level machine intelligence has long
been one of the basic objectives of AI. Officially, AI was born in 1956. Since
then, very impressive progress has been made in many areas—but not in the realm
of human level machine intelligence. Anyone who has been forced to use a dumb
automated customer service system will readily agree that human level machine
intelligence is not yet a reality. Today, no machine can pass the Turing test
and none is likely to do so in the foreseeable future. During much of its early
history, AI was rife with exaggerated expectations. A headline in an article
published in the late forties of last century was headlined, “Electric brain
capable of translating foreign languages is being built.” Today, more than half
a century later, we do have translation software, but nothing that can approach
the quality of human translation. Clearly, achievement of human level machine
intelligence is a challenge that is hard to meet. Humans have many remarkable
capabilities; there are two that stand out in importance. First, the capability
to reason, converse and make rational decisions in an environment of
imprecision, uncertainty, incompleteness of information and partiality of truth
and possibility. And second, the capability to perform a wide variety of
physical and mental tasks without any measurements and any computations. A
prerequisite to achievement of human level machine intelligence is mechanization
of these capabilities and, in particular, mechanization of natural language
understanding. In my view, mechanization of these capabilities is beyond the
reach of the armamentarium of AI—an armamentarium which in large measure employs
classical, Aristotelian, bivalent logic and bivalent-logic-based probability
theory. To make progress toward achievement of human level machine intelligence,
AI must add to its armamentarium concepts and techniques drawn from other
methodologies, especially evolutionary computing, neurocomputing and fuzzy
logic. A key contribution of fuzzy logic is the machinery of Computing with
Words (CW) and, more generally, NL-Computation. This machinery opens the door to
mechanization of natural language understanding and computation with information
described in natural language. Addition of this machinery to the armamentarium
of AI would be an important step toward the achievement of human level machine
intelligence and its applications in decision-making, pattern recognition,
analysis of evidence, diagnosis and assessment of causality. Such applications
have a position of centrality in medicine.
