Current Research
Ginsparg has recently used techniques from statistical mechanical models, specifically the Potts spin glass, to investigate community detection in networks. He has used these to develop new algorithms for clustering arXiv.org subject areas on the basis of full-text similarities, co-author networks, citation networks, and co-readership collaborative filtering.
