ActiveClassificationObject
represents the result of an ActiveClassification process.
Details and Options
- ActiveClassificationObject[…] is the result generated by ActiveClassification[…].
- ActiveClassificationObject[…][prop] gives the property prop of the active classification object.
- ActiveClassificationObject[…][{prop1,prop2,…}] gives the list of properties {prop1,prop2,…}.
- Possible properties include:
-
"EvaluationHistory" configurations explored and classes assigned to them "Method" method used for active classification "ClassifierFunction" best ClassifierFunction[…] obtained "ClassifierMeasurementsObject" latest ClassifierMeasurementsObject[…] obtained "LearningCurve" plot of mean cross-entropy evolution "Properties" list of all available properties
Examples
Basic Examples (1)
Train an ActiveClassifcationObject[…] to classify whether a number is greater than 0.5:
aco = ActiveClassification[# > 0.5&, RandomReal[{0.1, 1.2}]&]Obtain the list of object properties:
aco["Properties"]Obtain the history of explored configurations:
aco["EvaluationHistory"]Obtain the classifiers trained during active classification, along with their properties:
aco["TrainingHistory"]c = aco["ClassifierFunction"]Obtain the method used to choose configurations to add to the training set:
aco["Method"]aco[{"OracleFunction", "ClassifierMeasurementsObject"}]Display the performances of classifiers trained during active classification:
aco["LearningCurve"]Display the confusion matrix of the final classifier for a test set:
vals = RandomReal[{0.1, 1.2}, 70];
testset = # -> (# > 0.5)& /@ vals;
acM = ClassifierMeasurements[c, testset];
