We will show two possible applications of nearest neighbor
visualization. First, nearest neighbor visualization can
help users detect how regularities and outliers dynamically
emerge by gradually changing the control parameter value.
For example, a series of figures in Fig. 9 (on the last page)
show the emergence of regularities. Also, from the figure
c) in Fig. 9, we can see an outlier around the Bird block
emerges. It is Ostrich! Here, we did not use the color for
representing the different classes because we want to show
that the regularity is so clear and natural that it is almost
unnecessary to use colors.
