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);
}
}
}
