AcceptanceThreshold

AcceptanceThreshold

is an option that specifies the minimum threshold at which a result is considered acceptable.

Details

  • Typical settings include:
  • Automaticautomatic threshold
    vala numerical value typically between 0 and 1
  • Typically, if the confidence for a particular result is below the setting for AcceptanceThreshold, it will be rejected.
  • If all results are rejected, typically Missing[…] is returned.
  • In Classify, Predict and anomaly detection functions, the value of AcceptanceThreshold is used to define anomalies and corresponds to a RarerProbability threshold.

Examples

Basic Examples  (4)

Specify the acceptance threshold while detecting faces:

Wolfram Language code: FindFaces[[image], {"Image", "Strength"}, AcceptanceThreshold -> .8]//Dataset

Lower the threshold:

Wolfram Language code: FindFaces[[image], {"Image", "Strength"}, AcceptanceThreshold -> .5]//Dataset

ImageInstanceQ uses AcceptanceThreshold->0.5:

Wolfram Language code: ImageInstanceQ[[image], Entity["Concept", "Hawk::647j9"]]

With a higher recognition threshold, objects may not be identified:

Wolfram Language code: ImageInstanceQ[[image], Entity["Concept", "Hawk::647j9"], AcceptanceThreshold -> .9]

ImageIdentify uses an automatic acceptance threshold:

Wolfram Language code: ImageIdentify[[image]]

Specify a custom threshold:

Wolfram Language code: ImageIdentify[[image], AcceptanceThreshold -> .7]

If no identification is above the threshold, a Missing object is returned:

Wolfram Language code: ImageIdentify[[image], AcceptanceThreshold -> 1]

Delete anomalies with the default AcceptanceThreshold value:

Wolfram Language code: DeleteAnomalies[{1, 2, 4, 2, 4, 5, 8, 12}]

Delete anomalies with a higher threshold:

Wolfram Language code: DeleteAnomalies[{1, 2, 4, 2, 4, 5, 8, 12}, AcceptanceThreshold -> 0.1]
