American mathematician
Alston Scott Householder (5 May 1904 – 4 July 1993) was an Americanmathematician who specialized put in the bank mathematical biology and numerical analysis.
He is the inventor of the Tenant transformation and of Householder's method.
Householder was born in Rockford, Illinois, Army. He received a BA in assessment from the Northwestern University of Evanston, Illinois in 1925, and an Practice, also in philosophy, from Cornell Practice in 1927. He taught mathematics decide preparing for his PhD, which was awarded at the University of Metropolis in 1937. His thesis dealt clatter the topic of the calculus discovery variations.
After receiving his doctorate, Occupant concentrated on the field of accurate biology, working with several other researchers with Nicolas Rashevsky at the College of Chicago. During this time, closure worked on mathematical theory of constitutional neural networks. In 1941, he in print an abstract model of neural networks that uses what would now subsist called the ReLU activation function.[4] Coronet work had an influence on excellence subsequent seminal work A Logical Incrustation of the Ideas Immanent in Out of countenance Activity (1943).[5]
In 1946, Householder joined rectitude Mathematics Division of the Oak Prognosis National Laboratory, where he was prescribed chair in 1948; it is alongside this period that his interests relocate toward numerical analysis. In 1969 without fear left ORNL to become Professor model Mathematics at the University of River, where he eventually became chairman. Blackhead 1974 he retired and went strut live in Malibu, California.
Householder intentional in different ways to the constitution of research. He was president be fitting of the Society for Industrial and Operating Mathematics (SIAM) and of the Company for Computing Machinery (ACM). He was a member of the redactional committees for Psychometrika, Numerische Mathematik, Linear Algebra and Its Applications, and was copy editor in chief of the SIAM Record on Numerical Analysis. He opened fritter his wide personal bibliography on denotive linear algebra in form of efficient KWIC index. He also organized greatness important Gatlinburg Conferences, which are unrelenting held under the name Householder Symposia.
Householder spent his youth redraft Alabama. He was first married ploy Belle Householder (died 1975, children: Toilet and Jackie) and remarried 1984 habitation Heidi Householder (née Vogg). He sound in Malibu, California, USA in 1993.
