Something New about LDA and HDP

The UC Irvin team have updated their work and published a JMLR 2009 paper: Distributed Algorithms for Topic Models. For HDP, they proposed a greedy approach to matching of new topics. I also like their ways to visualize the training process.

Diane Hu, a PhD student working on latent topic models for musical analysis, recently wrote a tutorial/survey on LDA, Latent Dirichlet Allocation for Text, Images, and Music, which introduced LDA basics as well its extension models for images and music.
