AppendLayer

AppendLayer[]

represents a net layer that takes an input tensor and appends another tensor to it.

Details and Options

  • AppendLayer exposes the following ports for use in NetGraph etc.:
  • "Input"numerical tensor of rank n
    "Element"numerical tensor of rank n-1
  • AppendLayer is typically used inside NetGraph.
  • AppendLayer can operate on tensors that contain "Varying" dimensions.
  • AppendLayer[…][<|"Input"in,"Element"elem|>] explicitly computes the output from applying the layer, which is effectively given by Append[in,elem].
  • AppendLayer[…][<|"Input"->{in1,in2,…},"Element"->{elem1,elem2,…}|>] explicitly computes outputs for each of the ini and elemi.
  • AppendLayer[form,"port"->shape] allows the shape of the input or element port to be specified. Possible forms for shape are:
  • "Real"a single real number
    "Integer"a single integer
    na vector of length n
    {n1,n2,…}a tensor of dimensions n1×n2×…
    {"Varying",n2,n3,…}a variable-length sequence of tensors of dimensions n2×n3×…
