Extrapolation, Interpolation, and Smoothing of Stationary Time Series

With Engineering Applications


It has been the opinion of many that 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 work was circulated as a classified memorandum in 1942, as it was connected with sensitive war-time 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."

About the Author

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 science. He was the author of many books, with Cybernetics: On Control and Communication in the Animal and the Machine and God and Golem: A Comment on Certain Points Where Cybernetics Impinges on Religion among the most well-known.
