Table 5 Results for recovering the block constant structure in the MAPK microarray data [39]. (Left to Right) Recognition rates for: independently applied k-means, independent Gaussian mixture models (i-mix), alternating row and column hard assignment row column mixtures (rc-mix), sequentially optimized rc-mixtures (s-rc-mix) and variational optimization for rc-mixtures (v-rc-mix). We recover known, approximately block constant structure in a 36 × 67 element matrix with 7 row and 8 column classes.
