LinearDiscriminantFunction.Evaluate Method

Definition

Namespace: Numerics.NET.Statistics.Multivariate
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.1.5

Overload List

Evaluate(Vector<Double>) Evaluates the discriminant function at the specified point.
Evaluate(Matrix<Double>, Vector<Double>) Evaluates the discriminant function at the specified point.

Evaluate(Vector<Double>)

Evaluates the discriminant function at the specified point.
C# 
public double Evaluate(
	Vector<double> features
)

Parameters

features  Vector<Double>
The point at which to evaluate the function.

Return Value

Double
The value of the discriminant function at x.

Remarks

This method calculates the value of the linear discriminant function for a given feature vector. The discriminant function is a linear combination of the input features and the coefficients of the discriminant function, plus an intercept term. The result is a single scalar value that can be used to classify the input features into one of the predefined groups.

Evaluate(Matrix<Double>, Vector<Double>)

Evaluates the discriminant function at the specified point.
C# 
public Vector<double> Evaluate(
	Matrix<double> features,
	Vector<double>? scores = null
)

Parameters

features  Matrix<Double>
The point at which to evaluate the function.
scores  Vector<Double>  (Optional)
Optional. The vector to store the result in.

Return Value

Vector<Double>
A vector containing the value of the discriminant function for each row in features.

Remarks

This method calculates the value of the linear discriminant function for each row in a matrix of feature vectors. The discriminant function is a linear combination of the input features and the coefficients of the discriminant function, plus an intercept term. The result is a vector of scalar values that can be used to classify each row of input features into one of the predefined groups.
