.Fluxcreate_bias

			create_bias(weights, bias, size...)

Return a bias parameter for a layer, based on the value given to the constructor's keyword bias=bias.

• bias == true creates a trainable array of the given size, of the same type as weights, initialised to zero.

• bias == false returns false, which is understood by AD to be non-differentiable.

• bias::AbstractArray uses the array provided, provided it has the correct size. It does not at present correct the eltype to match that of weights.
