DATE:   Today, March 28, 2013

TITLE:  Interacting Bayesian Agents on Networks

ABSTRACT:  Consider a network of experts who try to predict if a certain 
movie will win an Oscar. When small groups of experts meet at various 
workshops and seminars they each state who is the more likely candidate to 
win in their view and then use Bayes rule to update their own private 
probability regarding the winner given what they've heard. This type of 
model has been studied extensively in theoretical economics. The main 
results proven in the economics literature concern the question of the 
convergence of opinions: do all experts end up agreeing on who is the more 
likely candidate to win? I will review some of the results from the 
economics literature and discuss a number of new results with Sly and 
Tamuz answering the questions of the aggregation power of this process: 
does this distributed process aggregate the information as well a 
centralized process?
