NetDelete

NetDelete[net,n]

deletes the n^(th) layer from a NetChain or NetGraph.

NetDelete[net,"name"]

deletes a named layer.

NetDelete[net,{spec1,spec2,…}]

deletes several layers simultaneously.

NetDelete[graph,NetPort["name"]]

deletes an output or state-input port from a NetGraph.

NetDelete[graph,{NetPort["name1"],NetPort["name2"],…}]

deletes several output or state-input ports simultaneously.

Details

  • NetDelete is typically used to remove a layer or a port in a net.
  • Layers can only be deleted from a chain or graph if their inputs and outputs are the same size, or if they are at the periphery of the network.

Basic Examples  (2)

Delete a layer from a chain:

Delete an output port from a graph:

Scope  (5)

Delete a layer from a chain, specifying the layer by name:

Delete a layer from a graph:

Delete multiple layers from a chain:

Delete multiple output ports from a graph:

Delete an input state port from a graph:

Possible Issues  (1)

If the layer being deleted is in the interior of a chain or graph, it must have exactly one input and output, which must be the same shape:
