Dear all,

This week on Thursday, Dr. Mehdi Molkaraie (UPF Barcelona, Spain) will
visit our lab and tell us about his work done at ETH Zurich, Switzerland
together with Prof. Andi Loeliger.

Note that the talk will start at *16.30* on *Thursday* in *P-312* (Pavillon
Roger-Gaudry).

Hope to see many of you there!

- Title: Partition Function of the Ising Model via Factor Graph Duality
- Abstract:
The partition function of a factor graph and the partition function of the
dual
factor graph are related to each other by the normal factor graph duality
theorem. We apply this result to the classical problem of computing the
partition function of the Ising model to show that, at low temperature,
Monte
Carlo methods are more efficient in the dual graphical model than the
original graphical model. The viability of the methods is demonstrated by
numerical experiments.

Based on a joint work with Prof H.-A. Loeliger (ETH-Zurich, Switzerland)
