NetAppend

NetAppend[net,layer]

appends a layer or a net onto a NetChain, a layer or a NetGraph with one output port.

NetAppend[net,"name"layer]

appends a layer with a given name.

NetAppend[net,{layer1,layer2,…}]

appends several layers or nets.

Details and Options

  • The input of the appended layer must be compatible with the output of the final layer in the chain.
  • Any NetDecoder attached to the end of the chain will be removed.
  • NetAppend[chain,layerspec,"Output"spec] can be used to specify a type for the output of the resulting chain, using the normal type specifications allowed by NetChain. The new port specification will replace any existing NetDecoder or type.
