31 October - 1 November 2003, The Logic of Time and Modality, PHILOG, Roskilde University (RUC)

Date: 31 October - 1 November 2003
Location: PHILOG, Roskilde University (RUC)
Costs: 75,00 DK/day
Deadline: 1 November 2003

Arthur Norman Prior (1914-69) was the founding father of the modern logic of time and modality. There is still a lot to learn from Prior's writings, and of Prior's last book Papers on Time and Tense. The conference "The Logic of Time and Modality", organized by PHILOG, aims to discuss the modern challenges, problems, and applications of the Priorean approach to the logic of time and modality.

6 November 2003, CWI INS4 seminar, Peter Grunwald

Date & Time: Thursday 6 November 2003, 16:00
Speaker: Peter Grunwald (CWI)
Title: Updating Probabilities
Location: CWI, Kruislaan 413c, room C001

(joint work with Joe Halpern, Cornell University, Ithaca, NY)
As examples such as the Monty Hall and the 3-prisoners puzzle show, applying conditioning to update a probability distribution on a ``naive space'', which does not take into account the protocol used, can often lead to counterintuitive results. We give a detailed explanation of this phenomenon. A criterion known as CAR (``coarsening at random'') in the statistical literature characterizes when ``naive'' conditioning in a naive space works. We provide two new characterizations of CAR. First we show that in many situations, CAR essentially *cannot* hold, so that naive conditioning must give the wrong answer. Second, we provide a procedural characterization of CAR, giving a randomized algorithm that generates all and only distributions for which CAR holds. Both results complement earlier work by Gill, van der Laan and Robins.

We also consider more generalized notions of update such as Jeffrey conditioning and minimizing relative entropy (MRE). We give a generalization of the CAR condition that characterizes when Jeffrey conditioning leads to appropriate answers, and show that there exist some very simple settings in which MRE essentially never gives the right results. This generalizes and interconnects previous results obtained in the literature on CAR and MRE.
