After observing that the nearest neighbor rule relies on the choice of a metric, we noted that in some instances, it makes sense for the metric to be independent of certain of the coordinates of the feature space. This brought up the subject of equivalence classes, and naturally invariant theory. Thus this lecture, allowing with the following three lectures, will be focused on invariant theory.
