"""Training of Neural Networks.
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."""
