NetPort

NetPort[{n,"port"}]

represents the specified port for layer number n in a NetGraph or similar construct.

NetPort[{"name","port"}]

represents the specified port for the layer with the specified name.

NetPort[spec,port]

is treated as equivalent to NetPort[{spec,port}].

NetPort["port"]

represents the specified input or output port for a complete net.

Details

  • When used in NetGraph, NetPort[{layer,"port"}] refers to the named output port of a layer when used on the left-hand side of a rule, and a named input port of a layer when used on the right-hand side of a rule.
  • When used in a NetGraph, NetPort["port"] refers to an input of the entire graph when used on the left-hand side of a rule, and an output of the entire graph when used on the right-hand side of a rule.
  • net[data,NetPort[oport]] can be used to obtain the value of the net at oport when it is applied to the specified data. oport must refer to an output port, a subnet of the net, or a layer.
  • net[data,{NetPort[oport1],NetPort[oport2],…}] returns an association <|NetPort[oport1]->…,NetPort[oport2]->…,…|> whose values are the values of the net at oporti when the net is applied to the specified data.
