The Training algorithms used when training on fann_train_data
with functions like
fann_train_on_data
or fann_train_on_file
. The incremental training alters the weights
after each time it is presented an input pattern, while batch only alters the weights once after
it has been presented to all the patterns.
Standard backpropagation algorithm, where the weights are updated after each training
pattern. This means that the weights are updated many times during a single epoch and some
problems will train very fast, while other more advanced problems will not train very well.
Standard backpropagation algorithm, where the weights are updated after calculating the mean
square error for the whole training set. This means that the weights are only updated once
during an epoch. For this reason some problems will train slower with this algorithm. But
since the mean square error is calculated more correctly than in incremental training, some
problems will reach better solutions.
A more advanced batch training algorithm which achieves good results for many problems.
Rprop
is adaptive and therefore does not use the learning_rate
. Some other parameters
can, however, be set to change the way Rprop
works, but it is only recommended for users
with a deep understanding of the algorithm. The original RPROP training algorithm is
described by [Riedmiller and Braun, 1993], but the algorithm used here is a variant, iRPROP,
described by [Igel and Husken, 2000].
A more advanced batch training algorithm which achieves good results for many problems. The
quickprop training algorithm uses the learning_rate
parameter along with other more
advanced parameters, but it is only recommended to change these for users with a deep
understanding of the algorithm. Quickprop is described by [Fahlman, 1988].
