"NotablePerson" (Built-in Classifier)

Determine the notable person in an image.

Classes

Details

  • The classifier is applied to the largest face found in the image.
  • The classifier will return one of the possible classes, even if the person in the input image is not among these classes.
  • In the current version, the notable persons are dominated by US-known personalities.

Basic Examples  (2)

Use the "NotablePerson" built-in classifier to determine what notable person is depicted in the given image:

Wolfram Language code: Classify["NotablePerson", [image]]

Obtain the probabilities for the most likely classes:

Wolfram Language code: Classify["NotablePerson", [image], "TopProbabilities"]

Obtain a ClassifierFunction for this classifier:

Wolfram Language code: c = Classify["NotablePerson"]

Use the classifier function to classify:

Wolfram Language code: c[[image]]

Classify many examples at once:

Wolfram Language code: c[{[image], [image]}]

Scope  (1)

Load the ClassifierFunction corresponding to the built-in classifier:

Wolfram Language code: c = Classify["NotablePerson"]

Obtain a subset of possible classes:

Wolfram Language code: Short[Information[c, "Classes"], 0.5]

Options  (3)

ClassPriors  (1)

Use a custom ClassPriors to restrict the possible outputs:

Wolfram Language code: Classify["NotablePerson", [image], ClassPriors -> <|Entity["Person", "GeorgeOrwell::9p9f8"] -> 0.5|>]

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold:

Wolfram Language code: Classify["NotablePerson", [image], IndeterminateThreshold -> 0.4]

UtilityFunction  (1)

Obtain the utility function of the classifier:

Wolfram Language code: utility = Information[Classify["NotablePerson"], "UtilityFunction"];
Wolfram Language code: utility[Entity["Person", "AmeliaEarhart::8t8s4"], Entity["Person", "MichaelCera::zb94m"]] = -3;

Classify an image using this new utility:

Wolfram Language code: Classify["NotablePerson", [image], UtilityFunction -> utility]

Compare to the result with the default utility:

Wolfram Language code: Classify["NotablePerson", [image]]

Neat Examples  (1)

Obtain different notable persons with their corresponding probabilities:

Wolfram Language code: probabilities = Classify["NotablePerson", [image], "Probabilities"];

Visualize a subset of results with the highest probabilities using WordCloud:
