New Paper in IEEE TVCG

My latest article, in IEEE Transactions on Visualization and Computer Graphics (IEEE TVCG), has been published online and is available via the IEEE Xplore Digital Library.  The paper was written with collaborators Nan Cao (IBM Research) and Yu-Ru Lin (Pittsburgh) and describes the UnTangle visualization technique for probabilistic multi-label data.  It is a followup to our recent ICDM paper, providing more details about the approach and new algorithms that produce improved results.
