Figure 1.

The conditional probability density functions p(Distance|Interaction) and p(Distance|Non-interaction) learned from embedding the components of the following four PPI networks into 20-dimentional Euclidean space: (a) Krogan, (b) DIP, (c) Tong, (d) DIP+BioGRID. The x axis denotes the distance between pairs of points in the embedding space and the y axis denotes the value of conditional probability density function.
