Theorems on Positive Data: On the Uniqueness of NMF
Figure 5
Data constructed as in Example 5 and plotted in the same manner as in
Figure 1, that is, the dashed triangle is the desired solution, the solid line
is the border of the dual of ,
and the shaded area is the positive span of .
In all the plots, equals and equals 0.01, 0.05, 0.1, and 0.15.
