Create Compute/State Node pair.
Create Compute/State Node pair. This selects between a spatial domain and frequency domain
implementation depending on the impl policy and other parameters.
the input signal DifferentiableField
the weight DifferentiableField for this convolution
the policy for supplying missing input values for border convolutions
the downsample factor applied to the output of the convolution
the policy for selecting the convolution implementation (spacial vs frequency domain)
The convolutional Node. The associated ConvolutionalState node
can be accessed as the in2 Node member of the returned node.
