In this RCC we will look at Bregman Divergences. I will describe the Bregman divergence and its properties and examine their relationship with exponential family distributions. I will also look at algorithms using Bregman divergences for clustering and other applications.

The discussion in mainly based on the paper: “Clustering with Bregman Divergences”, JMLR 6 , 2005 http://jmlr.csail.mit.edu/papers/volume6/banerjee05b/banerjee05b.pdf

Other related papers that I will reference include: “Matrix Nearness Problems with Bregman Divergences” http://authors.library.caltech.edu/9428/

“Learning Continuous Latent Variable Models with Bregman Divergences” http://www.springerlink.com/index/EHVDW71HTL8E05B3.pdf
