Loopy belief propagation for approximate inference: An empirical study. In:
- Proceedings of Uncertainty in AI,
, 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

to the correct marginals. However, on the QMR network, the loopy be liefs oscillated and had no obvious relation ship to the correct posteriors. We present some initial investigations into the cause of these oscillations, and show that some sim ple methods of preventing them lead to the wrong results
Everyone Wants a Chance: Initial Positions and Fairness in Ultimatum Games
, 2012
"... We investigate experimentally the modification of initial chances to acquire advantaged positions in bargaining problems. In the baseline case players have equal opportunities to acquire the advantaged position. Chances become increasingly unequal across three treatments. We find: (1) The more unequ ..."

Everyone Wants (at Least) One Chance: Experiments on Lotteries Assigning Initial Positions

An Algorithm for Probabilistic Planning
, 1995
"... We define the probabilistic planning problem in terms of a probability distribution over initial world states, a boolean combination of propositions representing the goal, a probability threshold, and actions whose effects depend on the execution-time state of the world and on random chance. Adoptin ..."

Generating textures on arbitrary surfaces using reaction-diffusion
- Computer Graphics
, 1991
"... This paper describes a biologically motivated method of texture synthesis called reaction-diffusion and demonstrates how these textures can be generated in a manner that directly matches the geometry of a given surface. Reaction-diffusion is a process in which two or more chemicals diffuse at unequa ..."

Biologists and mathematicians have explored the patterns made by several reaction-diffusion systems. We extend the range of textures that have previously been generated by using a cascade of multiple
Metaanalysis of theory-of-mind development. The truth about false belief.
- Child Development,
, 2001
"... Research on theory of mind increasingly encompasses apparently contradictory findings. In particular, in initial studies, older preschoolers consistently passed false-belief tasks-a so-called "definitive" test of mentalstate understanding-whereas younger children systematically erred. Mor ..."

Progressive search space reduction for human pose estimation
- In CVPR
, 2008
"... The objective of this paper is to estimate 2D human pose as a spatial configuration of body parts in TV and movie video shots. Such video material is uncontrolled and extremely challenging. We propose an approach that progressively reduces the search space for body parts, to greatly improve the chan ..."

the chances that pose estimation will succeed. This involves two contributions: (i) a generic detector using a weak model of pose to substantially reduce the full pose search space; and (ii) employing ‘grabcut ’ initialized on detected regions proposed by the weak model, to further prune the search space
The Complexity of Stochastic Games
- Information and Computation
, 1992
"... We consider the complexity of stochastic games -- simple games of chance played by two players. We show that the problem of deciding which player has the greatest chance of winning the game is in the class NP " co-NP. 1 Introduction We consider the complexity of a natural combinatorial problem ..."

A theory of political transitions
- American Economic Review
, 2001
"... We develop a theory of political transitions inspired in part by the experiences of Western Europe and Latin America. Nondemocratic societies are controlled by a rich elite. The initially disenfranchised poor can contest power by threatening social unrest or revolution, and this may force the elite ..."

Unequal Chances in Education: Educational Inequalities in the Czech Republic

One would presume that the Czech Republic, giv-en its egalitarian tradition and track record of redistributive social transfers, would also have developed an education system that eq ..."
