Figure 8

Proportion of proteins corresponding to given functional sites coverage. This figure shows functional coverage variation of NMF, original PPA, block random, and point random basis vectors. The x-axis represents the detection ratio of functional sites, the y-axis the proportion of proteins. ScanProsite gives predicted functional sites. NMF and PPA denote the NMF basis vectors and original PPA vectors. Block (Point) random basis vector are build by rearrange blocks (points) in NMF basis vectors. Figure shows that NMF basis vectors match with functional sites more than other vectors.
