SummationLayer

SummationLayer[]

represents a net layer that sums all of its input elements.

Details and Options

  • SummationLayer[…][input] explicitly computes the output from applying the layer.
  • SummationLayer[…][{input1,input2,…}] explicitly computes outputs for each of the inputi.
  • SummationLayer exposes the following ports for use in NetGraph etc.:
  • "Input"a tensor of arbitrary rank
    "Output"a real number
  • SummationLayer is typically used inside NetChain, NetGraph, etc.
  • When it cannot be inferred from other layers in a larger net, the option "Input"->{n1,n2,…} can be used to fix the input dimensions of SummationLayer.
