# IRegressionLoss Interface

## Definition

public interface IRegressionLoss : Microsoft.ML.Trainers.ILossFunction<float,float>, Microsoft.ML.Trainers.IScalarLoss
type IRegressionLoss = interface

## Methods

 Derivative of the loss function with respect to output (Inherited from IScalarLoss) Computes the loss given the output and the ground truth. Note that the return value has type Double because the loss is usually accumulated over many instances. (Inherited from ILossFunction)
