DESCRIPTION:Graphical models provide a powerful framework for reasoning ab
 out latent explanations of data\,\nand for integrating different sources o
 f information.  But several practical issues result in them\nbeing applied
  less often than they could be.  I will discuss a recent application aroun
 d inferring the \nlocation of boxes in a supply chain from RFID data.  Thi
 s application is instructive \nbecause it highlights a few of these limita
 tions and presents opportunities for new methodology.\n\nFinally\, I will 
 discuss how we are attempting to address another practical barrier to appl
 ying\ngraphical models\, namely\, scalability of inference techniques.   I
  will describe some very recent work\non new methods for approximate infer
 ence that make use of approximate second-order information\,\nwithin a qua
 si-Newton framework.\n
