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
	n	a 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 in_i and element_i.
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.
