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

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)
