AppendLayer

AppendLayer[]

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

Details and Options

  • AppendLayer exposes the following input ports for use in NetGraph etc.:
  • "Input"an array of rank n
    "Element"an array of rank n-1
  • AppendLayer exposes the output port "Output", which is an array of rank n.
  • AppendLayer is typically used inside NetGraph.
  • AppendLayer["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,…}an array of dimensions n1×n2×…
    {"Varying",n2,n3,…}an array whose first dimension is variable and remaining dimensions are n2×n3×…
  • 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"{element1,element2,…}|>] explicitly computes outputs for each of the ini and elementi.
  • When given a NumericArray as input, the output will be a NumericArray.
  • Options[AppendLayer] gives the list of default options to construct the layer. Options[AppendLayer[…]] gives the list of default options to evaluate the layer on some data.
  • Information[AppendLayer[…]] gives a report about the layer.
  • Information[AppendLayer[…],prop] gives the value of the property prop of AppendLayer[…]. Possible properties are the same as for NetGraph.
