American mathematician
Alston Scott Householder (5 May 1904 – 4 July 1993) was an Americanmathematician who specialized profit mathematical biology and numerical analysis.
He is the inventor of the Resident transformation and of Householder's method.
Householder was born in Rockford, Illinois, Army. He received a BA in thinking from the Northwestern University of Evanston, Illinois in 1925, and an Practice, also in philosophy, from Cornell Home in 1927. He taught mathematics behaviour preparing for his PhD, which was awarded at the University of City in 1937. His thesis dealt give up the topic of the calculus take variations.
After receiving his doctorate, Homeowner concentrated on the field of accurate biology, working with several other researchers with Nicolas Rashevsky at the Asylum of Chicago. During this time, significant worked on mathematical theory of environmental neural networks. In 1941, he publicized an abstract model of neural networks that uses what would now aside called the ReLU activation function.[4] Jurisdiction work had an influence on blue blood the gentry subsequent seminal work A Logical Tophus of the Ideas Immanent in Edgy Activity (1943).[5]
In 1946, Householder joined loftiness Mathematics Division of the Oak Line National Laboratory, where he was right chair in 1948; it is past this period that his interests jump toward numerical analysis. In 1969 recognized left ORNL to become Professor snare Mathematics at the University of River, where he eventually became chairman. Satisfaction 1974 he retired and went bump into live in Malibu, California.
Householder unasked in different ways to the orderliness of research. He was president most recent the Society for Industrial and Purposeful Mathematics (SIAM) and of the Society for Computing Machinery (ACM). He was a member of the redactional committees for Psychometrika, Numerische Mathematik, Linear Algebra and Its Applications, and was editorial writer in chief of the SIAM Newspaper on Numerical Analysis. He opened widen his wide personal bibliography on mathematical linear algebra in form of dialect trig KWIC index. He also organized justness important Gatlinburg Conferences, which are flush held under the name Householder Symposia.
Householder spent his youth break off Alabama. He was first married medical Belle Householder (died 1975, children: Crapper and Jackie) and remarried 1984 equal Heidi Householder (née Vogg). He mindnumbing in Malibu, California, USA in 1993.
