# VNClassificationObservation An object that represents classification information that an image-analysis request produces. ``` class VNClassificationObservation ``` ## Overview This type of observation results from performing a [`VNCoreMLRequest`](/documentation/Vision/VNCoreMLRequest) image analysis with a Core ML model whose role is classification (rather than prediction or image-to-image processing). Vision infers that an object is a classifier model if that model predicts a single feature. That is, the model’s object has a non-`nil` value for its property. ## Topics ### Determining Classification [`identifier`](/documentation/Vision/VNClassificationObservation/identifier) Classification label identifying the type of observation. ### Measuring Confidence and Precision [`hasPrecisionRecallCurve`](/documentation/Vision/VNClassificationObservation/hasPrecisionRecallCurve) A Boolean variable indicating whether the observation contains precision and recall curves. [`hasMinimumPrecision(_:forRecall:)`](/documentation/Vision/VNClassificationObservation/hasMinimumPrecision(_:forRecall:)) Determines whether the observation for a specific recall has a minimum precision value. [`hasMinimumRecall(_:forPrecision:)`](/documentation/Vision/VNClassificationObservation/hasMinimumRecall(_:forPrecision:)) Determines whether the observation for a specific precision has a minimum recall value. --- Copyright © 2026 Apple Inc.
