fann_get_cascade_output_change_fraction - Returns the cascade output change fraction

SYNOPSIS

       float fann_get_cascade_output_change_fraction (resource	$ann)

DESCRIPTION

	The cascade output change fraction is a number between 0 and 1 determining how large a fraction of the fann_get_MSE(3) value should change
       within fann_get_cascade_output_stagnation_epochs(3) during training of the output connections, in order for the training not  to  stagnate.
       If the training stagnates, the training of the output connections will be ended and new candidates will be prepared.

	It  means  that  if  the  MSE does not change by a fraction of fann_get_cascade_output_change_fraction(3) during a period of fann_get_cas-
       cade_output_stagnation_epochs(3), the training of the output connections is stopped because the training has stagnated.

	If the cascade output change fraction is low, the output connections will be trained more and if  the  fraction  is  high,  they  will	be
       trained less.

	The default cascade output change fraction is 0.01, which is equalent to a 1% change in MSE.

PARAMETERS

	      o $ann
		-Neural network resource.

RETURN VALUES

	The cascade output change fraction, or FALSE on error.
