    Syntax

    Y = deep.transform.ismax(X)

    Description

    Y = deep.transform.ismax(X) applies the is-maximum mask transform to the input X. When you convert a Statistics and Machine Learning Toolbox™ neural network model that uses an is-maximum mask score transform to a dlnetwork object, the last layer of the network is a function layer that applies the deep.transform.ismax function.

    Apply the is-maximum mask transform to random data.

    X = rand(3,5);
X = dlarray(X,"CB");
Y = deep.transform.ismax(X)
    Y = 
  3(C) × 5(B) dlarray

    Create a function layer that applies the is-maximum mask transform.

    layer = functionLayer(@deep.transform.ismax)
    layer = 
  FunctionLayer with properties:
