NetReplace

NetReplace[net,pattlayer]

gives a net in which all layers matching patt are replaced with layer.

NetReplace[net,{rule1,rule2,}]

performs all replacements specified by the rulei.

Details and Options

  • The patterns can be either expressions that match a specific net head, such as _ElementwiseLayer, or literal layers, such as ElementwiseLayer[Ramp].
  • When a literal layer is matched, all user-provided parameters must match exactly. Input and output dimensions need not match.
  • Layers will be matched at any depth in the original net.
  • If the replacement value is Nothing, the corresponding layer of the net will be dropped.
  • If no replacements are performed, a message will be issued and the original net will be returned.
