Whitepaper: Cross-Entropy Directed Embedding of Network Data

by NTT CommunicationsJan 01, 2008

Unlike existing methods, the proposed method in this paper attempts to minimize an energy function based on the cross-entropy between desirable and embedded node configurations without directly utilizing pairwise distances between nodes. The white paper proposes a natural criterion to effectively evaluate an embedded network layout in terms of how well node connectivities are preserved. Experimental results show that the proposed method provides better layouts than those produced by some of the
