Time-Sensitive Dirichlet Process Mixture Models

  title={Time-Sensitive Dirichlet Process Mixture Models},
  author={Xiaojin Zhu and Zoubin J. C. Ghahramani and John D. Lafferty},
We introduce Time-Sensitive Dirichlet Process Mixture mod els for clustering. The models allow infinite mixture components just like standard Dirichlet process mixture models. However they also have the ability to model time corr elations between instances. Research supported in part by NSF grants NSF-CCR 0122481, NSF-I IS 0312814, and NSFIIS 0427206. Zoubin Ghahramani was supported at CMU by DARPA un der the CALO project.
