5.1.2.2 Categorization as a function of the number of nnn-zcro clemcnLs in the S2-C2
weight matrix
Figures 5.12. 5.13, 5.14 and 5.15 show the categorization peifomiance as a function oC the
number of non-zero elements in the S2-C2 weigh! matrix (see Section 4.3 for details), for the
four different S2 RF sizes. Results were obtained for the alicmative 3-leveI architecture using
values of Kcigmup = licigmup - 10. and are plotted for the five diffcreni lesi dalasets as detailed
in the figure legend.
