Activation function pointer

Activation function derivative pointer

[protected]

Number of neurons in the layer

[protected]

Number of input neurons

[protected]

Pointer to the weight vector

[protected]

[protected]

Offset of the layer weight vector in the network weight vector

[protected]

Offset of the layer's first neuron in the list of all network neurons (not too sure about that one, though)

[protected]

Offset of the layer's first neuron derivative in the list of all network neurons

This (empty) constructor is used for parsing a layer from a file

Standard constructor

Unimplemented yet (not sure if we *should* implement it)

Called after reading a layer to setup the weight vector correctly

Calculates all the activation functions (and derivatives) for a given input

Layer size

Number of weights

Offset of a certain neuron's weight vector relative to the whole network's weight vector

Initializes the layer values given the means and standard deviations of each of the inputs

Sets the bias vector

[const]

Writes the layer to a stream

Reimplemented from Object.

Reads the layer from a stream (remember to call setupAfterRead after that

Reimplemented from Object.
