Commenti

CoreML non legge e scrive dati nativi del sistema direttamente. Usa invece questa classe per eseguire il mapping delle stringhe ai valori per gli input e gli output dell'oggetto MLModel .

Nell'esempio seguente viene illustrato un che fornisce 3 variabili di input, tutti di tipo 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);
		}
	}
}
