model {GGClassification}

Calculates the parameters of a large-margin classifier based on the Gabriel Graph.

Description

The function computes the Gabriel Graph and applies a filter on the graph to remove noise in the margin region.

Then a new Graph is calculated considering the filtered data, and the parameters of a large-margin classifier are obtained and returned as a named list.

Usage

model(X, y, normalize=FALSE)

Arguments

X

Matrix containing data.

y

Vector of labels.

normalize

If data should be normalized or not.

Value

A named list containing the parameters of the classifier.
