The von Neuman-Morgenstern utility functions play a relevant role in
the set of utility functions. This paper shows the density of the set von Neuman-
Morgenstern utility functions on the set of utility utility function that can represent
arbitrarily well a given continuous but not independent preference relation over
monetary lotteries. The main result is that without independence it is possible to
approximate utility functions over monetary lotteries by von Neuman-Morgenstern
ones with arbitrary precision. The approach used is a constructive one. Neural networks
are used for their approximation properties in order to get the result, and their
functional form provides both the von Neumann-Morgenstern representation and
the necessary change of variables over the set of lotteries.
