      Erwin Bolthausen (Universität Zürich, Switzerland): Approximate message passage and the TAP equation

      Abstract: Message passage is a method to approximately compute marginal distributions of probability distributions having an underlying graphical structure. It was reinvented several times. One of its first appearances was in decoding algorithms for error correcting codes. More recently, versions of it where used as an alternative to LASSO type methods in compressed sensing. Depending on the underlying graphical structure, it is possible to reduce the algorithmic complexity by an approximation step which results in what is called “Approximate Message Passage”. The high efficiency of the corresponding algorithms in compressed sensing was first observed numerically by Donoho and Montanari. A theoretical understanding was first obtained in spin glass theory where it is closely connected with the Thouless-Anderson-Palmer equation.

The talk aims at giving an overview. If the time allows, we will present some recent developments of the AMP-TAP approach to compute free energies.

About PVSeminar

This online probability seminar is an initiative of Probability Victoria group, inspired by the example of One World Probability seminar.

One World Probability seminar was a great initiative. From our time zone (UTC+10/11) and other countries in East Asia and Oceania perspective, its main drawback is that it is run around midnight. So we thought it would be great to have an additional online seminar run at a time more suitable for our region (but also acceptable for some other parts of the world).

The seminar is supposed to be run on Zoom weekly (or fortnightly, depending on the availability of speakers), on Thursdays, usually starting at 17:00 or 19:00 AEST (Australian East Standard Time, UTC+10, the timezone of Melbourne & Sydney) or AEDT (Australian Eastern Daylight Time, UTC+11, the daylight saving timezone of Melbourne & Sydney). Please check the time difference between your timezone and AEST/AEDT — and beware of the switches to/from daylight saving time that tend to occur from time to time.

If you sign to our seminar mailing list, you will receive a Zoom link to the webinar a few days before the talk. This link will also appear on this Website.
