Purpose

Demonstrate nearest neighbour classifier.

Synopsis

demknn1

Description

The problem consists of data in a two-dimensional space. The data is drawn from three spherical Gaussian distributions with priors 0.3, 0.5 and 0.2; centres (2, 3.5), (0, 0) and (0,2); and standard deviations 0.2, 0.5 and 1.0. The first figure contains a scatter plot of the data. The data is the same as in demgmm1.

The second figure shows the data labelled with the corresponding class given by the classifier.
