We develop a. new feedforward neuralnet.work represent.ation of Lipschitz functions from [0, p]n into [0,1] ba'3ed on the level sets of the function. We show that
~~ + ~€r + ( 1 + h) (:~) n
is an upper bound on the number of nodes needed to represent f to within uniform error Cr, where L is the Lipschitz constant. \Ve also show that the number of bits needed to represent the weights in the network in order to achieve this approximation is given by
o (~2;~r (:~) n) .
\Ve compare this bound with the [-entropy of the functional class under consideration.
