class RNeuralnet(RPackage):
"""Training of neural networks using backpropagation, resilient
backpropagation with (Riedmiller, 1994) or without weight backtracking
(Riedmiller and Braun, 1993) or the modified globally convergent version by
Anastasiadis et al. (2005). The package allows flexible settings through
custom-choice of error and activation function. Furthermore, the calculation of
generalized weights (Intrator O & Intrator N, 1993) is implemented."""
