LeastSquaresGradientFunction Delegate

Gradient function delegate.

Namespace: Accord.Math.Optimization
Assembly: Accord.Math (in Accord.Math.dll) Version: 3.8.0

Syntax

Copy

public delegate void LeastSquaresGradientFunction(
	double[] parameters,
	double[] input,
	double[] result
)

Public Delegate Sub LeastSquaresGradientFunction ( 
	parameters As Double(),
	input As Double(),
	result As Double()
)

Parameters

parameters: Type: SystemDouble
The function parameters, also known as weights or coefficients.
input: Type: SystemDouble
An input vector.
result: Type: SystemDouble
The resulting gradient vector (w.r.t to the parameters).

Remarks

This delegate represents the gradient of a Least Squares objective function. This function should compute the gradient vector in respect to the function parameters.
