It is known a priori that the pattern points in category 1 tend to cluster close to
some central cluster point X1 , and that the pattern points in category 2 tend to
cluster close to another cluster point X2 . The coordinates of the points Xi and X ...

Several such ellipsoidal clusters of pattern points are illustrated in Fig . 3 . 3 . One
cluster might contain patterns belonging to category 1 ; another might contain
patterns belonging to category 2 , etc . For each category a cluster of pattern
points ...

It seems reasonable to assume that the k closest training patterns to a given
pattern X will often include a predominant number of patterns from the cluster
surrounding the closest mode . Thus the " closest - mode " method just described
will ...
