Hi all,
Toby Hocking will be joining us Friday afternoon to give a talk on clustering. Please be there.
When: 4pm Friday June 22, 2012. Where: AA3195
Title/Abstract:
"Clusterpath: An Algorithm for Clustering using Convex Fusion Penalties"
http://www.icml-2011.org/papers/419_icmlpaper.pdf
Abstract: We present a new clustering algorithm by proposing a convex relaxation of hierarchical clustering, which results in a family of objective functions with a natural geometric interpretation. We give efficient algorithms for calculating the continuous regularization path of solutions, and discuss relative advantages of the parameters. Our method experimentally gives results similar to spectral clustering for non-convex clusters, and has the added benefit of learning a tree structure from the data.
