OutputPorts

OutputPorts

is an option to specify the number, names or shapes of output ports for some neural net layers.

Details

  • OutputPorts is typically used in PlaceholderLayer.
  • Typical settings for OutputPorts include:
  • Automaticinfer number of ports and their shapes from NetChain or NetGraph connectivity
    nn ports with default names and unspecified shapes
    {"name1","name2",…}explicit port names with unspecified shapes
    {shape1,shape2,…}default port names with specified shapes or encoders
    <|"name1"shape1,…|>explicit port names with specified shapes or encoders
  • Shape specifications for each port include:
  • "Real"a single real number
    "Integer"a single integer
    Restricted["Integer",n]an integer between 1 and n
    na vector of length n
    {n1,n2,…}an array of dimensions n1×n2×…
    "Varying"a vector whose length is variable
    {"Varying",n2,n3,…}an array whose first dimension is variable and remaining dimensions are n2×n3×…
    NetDecoder[…]a decoder

Basic Examples  (1)

By default, PlaceholderLayer has a single output port:

Use OutputPorts to create a PlaceholderLayer with three ports having default names and unspecified shapes:

Scope  (3)

Create a PlaceholderLayer with two outputs having explicit names and unspecified shapes:

Create a PlaceholderLayer with four outputs having default names and specified shapes:

Create a PlaceholderLayer with two outputs having explicit names and specified shapes:
