A Conversation with Hirotugu Akaike
Hirotugu Akaike was born in Fujinomiya City, Shizuoka Prefecture, Japan on the fifth of November 1927. He studied at the Naval Academy of Japan, the First Higher School and the University of Tokyo, where he earned his B.S. degree and his external Doctor of Science degree, both in mathematics.
After receiving his bachelor’s degree in 1952, he was hired by the Institute of Statistical Mathematics, which had been founded eight years earlier by the Japanese government. He was Director of the institute’s Fifth Division, concerned with time series analysis and control, from 1973 until 1985. When the institute was reorganized as an interuniversity research institute in 1986, he became a Professor and Director of the Department of Prediction and Control. In 1987, he became Director General of the Institute, the position from which he retired on March 31, 1994. He was also Professor and Head of the Department of Statistical Science of the Graduate University for Advanced Studies, an independent university whose departments are distributed among the 11 interuniversity research institutes, from 1988 until 1994.
He has held visiting positions at a number of universities: Princeton (1966–1967), Stanford (1967, 1979), Hawaii (1972), the University of Manchester Institute of Science and Technology (1973), Harvard (Vinton Hayes Senior Fellow in Engineering and Applied Physics, 1976), Wisconsin—Madison (Mathematics Research Center, 1982) and several Japanese universities.
His honors include two major technology prizes, each shared with one or more collaborating engineers: with Toichiro Nakagawa, he was awarded the 1972 Ishikawa Prize for modernization of production management by the Ishikawa Prize Committee of the Japan Union of Scientists and Engineers; and, with Hideo Nakamura and others, he received the 1980 Okochi Prize of the Okochi Memorial Foundation for contributions to production engineering. In 1989, he was the recipient of two of Japan’s most respected culture and science awards, the Purple Ribbon Medal given by the Emperor of Japan and the Asahi Prize of the Asahi Shimbun Foundation, awards which recognize writers and artists and other citizens as well as inventors and scientists for distinguished contributions to Japanese society. He was a member of the Science Council of Japan from 1988 to 1991.
He has published more than 140 papers and several monographs and textbooks. His 1972 monograph with T. Nakagawa on the statistical analysis and control of dynamic systems has been republished in English translation (Akaike and Nakagawa, 1988). To indicate the magnitude of the impact of the methods described in this book, Professor Genshiro Kitagawa kindly provided us with a table from an article published in Japan in February 1994 listing the outputs of electric power plants in Japan that were built to be controlled by statistical models based on these methods. The table shows these plants generated approximately 12% of Japan’s electrical power obtained from nonnuclear and nonhydroelectric sources.
The initial conversation, in which David Findley and Emanuel Parzen spoke with Professor Akaike, took place in May 1992 at the University of Tennessee in Knoxville during the “First U.S.—Japan Conference on the Frontiers of Statistical Modeling: An Information Approach.” Findley later obtained clarifications and amplifications of some points from Professor Akaike during visits to the Institute of Statistical Mathematics in Tokyo in March 1993 and February 1994.
