Constructor & Destructor Documentation

Layer	(	int	size,
		double	factor_bias = 0.1,
		ActivationFunction	actfun = FeedForwardNN::linear
	)

constructor for Layer.

The derivative and inverse of activation function is derived automatically.

Parameters:

	size	number neurons
	factor_bias	size of bias neuron , if 0 no bias is used
	actfun	activation function. see also FeedForwardNN

Layer	(	int	size,
		double	factor_bias,
		ActivationFunction	actfun,
		ActivationFunction	dactfun
	)			[inline]

obsolete, use the other constructor for Layer.

Parameters:

	size	number neurons
	factor_bias	size of bias neuron , if 0 no bias is used
	actfun	activation function. see also FeedForwardNN
	dactfun	derivative of activation function (should be consistent with actfun)
