VNCoreMLFeatureValueObservation

A collection of key-value information produced by a Core ML image analysis request.

Overview

This type of observation results from performing a VNCoreMLRequest image analysis with a Core ML model whose role is prediction (rather than classification or image-to-image processing). Vision infers that an MLModel object is a predictor model if that model predicts multiple features—that is, the model's modelDescription object has a nil value for its predictedFeatureName property (and instead describes its outputs in an outputDescriptionsByName dictionary).
