Extrapolation, Interpolation, and Smoothing of Stationary Time Series

A book thatbecame the basis for modern communication theory, by a scientist considered one of the founders of the field of artifical intelligence.

Some predict that Norbert Wiener will be remembered for his Extrapolation long after Cybernetics is forgotten. Indeed, few computer science students would know today what cybernetics is all about, while every communication student knows what Wiener's filter is. The original work was circulated as a classified memorandum in 1942, because it was connected with sensitive wartime efforts to improve radar communication. This book became the basis for modern communication theory, by a scientist considered one of the founders of the field of artifical intelligence. Combining ideas from statistics and time-series analysis, Wiener used Gauss's method of shaping the characteristic of a detector to allow for the maximal recognition of signals in the presence of noise. This method came to be known as the "Wiener filter."

Norbert Wiener (1894–1964) served on the faculty in the Department of Mathematics at MIT from 1919 until his death. In 1963, he was awarded the National Medal of Science for his contributions to mathematics, engineering, and biological sciences. He was the author of many books, including Norbert Wiener—A Life in Cybernetics and the National Book Award-winning God & Golem, Inc.: A Comment on Certain Points Where Cybernetics Impinges on Religion (both published by the MIT Press).
