Definition

Namespace:

CoreML

Assembly:

Xamarin.iOS.dll

An interface that defines input or output features and allows access to their values.

Remarks

CoreML does not directly read and write system-native data. Rather it uses this class to map strings to values for the inputs and outputs of the MLModel object.

The following example shows a T:Monotouch.CoreML.IMLFeatureProvider that provides 3 inputs variables, all of type double:

public class MarsHabitatPricerInput : NSObject, IMLFeatureProvider
{
	public double SolarPanels { get; set; }
	public double Greenhouses { get; set; }
	public double Size { get; set; }

	public NSSet<NSString> FeatureNames => new NSSet<NSString>(new NSString("solarPanels"), new NSString("greenhouses"), new NSString("size"));

	public MLFeatureValue GetFeatureValue(string featureName)
	{
		switch (featureName)
		{
			case "solarPanels":
				return MLFeatureValue.Create(SolarPanels);
			case "greenhouses":
				return MLFeatureValue.Create(Greenhouses);
			case "size":
				return MLFeatureValue.Create(Size);
			default:
				return MLFeatureValue.Create(0);
		}
	}
}

Properties

FeatureNames	The names of the feature, as defined by the MLModel.
Handle	Handle (pointer) to the unmanaged object representation. (Inherited from INativeObject)

Methods

GetFeatureValue(String)

Retrieves the value of the .
