RegressionGradientFunction Delegate

Gradient function delegate.

Namespace: Accord.Statistics.Models.Regression
Assembly: Accord.Statistics (in Accord.Statistics.dll) Version: 3.8.0

Syntax

Copy

public delegate void RegressionGradientFunction(
	double[] coefficients,
	double[] input,
	double[] result
)

Public Delegate Sub RegressionGradientFunction ( 
	coefficients As Double(),
	input As Double(),
	result As Double()
)

Parameters

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

Remarks

This delegate represents the gradient of regression function. A regression function is a parameterized function that, given a set of coefficients and an input vector, produces an associated output value. This function should compute the gradient vector in respect to the function coefficients.
