VNCoreMLFeatureValueObservation

An object that represents a collection of key-value information that a Core ML image-analysis request produces.

Declaration

class VNCoreMLFeatureValueObservation

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. You can tell that a model predicts multiple features when its modelDescription object has a nil value for its predictedFeatureName property, or when it inserts its output in an outputDescriptionsByName dictionary.
