Browder), 1976. In the article on Hilbert's 13th problem, reference is made to Kolmogorov's proof concerning the approximation of any continous function of N variables using only linear summations and nonlinear but continously increasing functions of only one variable. (shades of typical backprop n.n.'s with logistic activation functions!). In any case, I have this book on recall at my own library and doubt whether it will arrive in time for a seminar I'm giving next Wednesday. If anyone has any information - in particular about Kolmogorov's theorem - I'd appreciate an email response. Thanks!
