ABSTRACT
Neural networks are dense in the space of dynamical systems. We present
a Monte Carlo study of the dynamic properties along the route to chaos
over random dynamical system function space by randomly sampling the neural
network function space. Our results show that as the dimension of
the system (the number of dynamical variables) is increased, the probability
of chaos approaches unity. We present theoretical and numerical results
which show that as the dimension is increased, the quasiperiodic route
to chaos is the dominant route. We also qualitatively analyze the
dynamics along the route.
