Detailed Description

The NeuronLayer is an interface for layers that take one blob as input (x) and produce only equally-sized blob as output (y), where each element of the output depends only on the corresponding input element.

The NeuralLayer is the base class for all 'neuron' classes that alter the input data, but not its shape.

Template Parameters

T	Specifies the base type float or double. Using float is recommended to conserve GPU memory.
