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 ..."

nothing directly to do with coding or decoding will show that in some sense belief propagation "converges with high probability to a near-optimum value" of the desired belief on a class of loopy DAGs Progress in the analysis of loopy belief propagation has been made for the case of networks
Unrealistic optimism about future life events.
- Journal of Personality and Social Psychology,
, 1980
"... Two studies investigated the tendency of people to be unrealistically optimistic about future life events. In Study 1, 258 college students estimated how much their own chances of experiencing 42 events differed from the chances of their classmates. Overall, they rated their own chances to be above ..."

to be above average for positive events and below average for negative events, ps<.001. Cognitive and motivational considerations led to predictions that degree of desirability, perceived probability, personal experience, perceived controllability, and stereotype salience would influence the amount
Probability, Rational Belief, and Belief Change
"... A simple model of rational belief holds that: (i) an instantaneous snapshot of an ideally rational belief system corresponds to a probability distribution; and (ii) rational belief change occurs by Bayesian conditionalization. But a priori probability distributions of the Kolmogorov sort cannot dist ..."

On belief change in ontology evolution.
- Summary.
, 2006
"... We study the feasibility of applying the dominating paradigm of belief revision, the AGM theory, to logics outside its original scope, with special emphasis given on logics used for ontological representation in the Semantic Web. Such an application would allow determining whether a proposed change ..."

change operator (e.g., an ontology evolution algorithm) behaves rationally or not. We give a number of interesting theoretical results related to the (generalized) AGM theory and show that our work can find important applications in dynamic environments employing non-classical logical formalisms. We
Believing Change and Changing Belief
- IEEE Transactions on Systems, Man, and Cybernetics Special Issue on Higher-Order Uncertainty
, 1996
"... We present a first-order logic of time, chance, and probability that is capable of expressing the four types of higher-order probability sentences relating subjective probability and objective chance at different times. We define a causal notion of objective chance and show how it can be used in con ..."

Furthermore, the semantics of the logic captures some
Relation of threatened egotism to violence and aggression: The dark side of high self-esteem
- In
, 1999
"... Conventional wisdom has regarded low self-esteem asan important cause of violence, but the oppo-site view is theoretically viable. An interdisciplinary review of evidence about aggression, crime, and violence contradicted the view that low self-esteem is an important cause. Instead, violence appears ..."

Inflated, unstable, or tentative beliefs in the self's uperi-ority may be most prone to encountering threats and hence to causing violence. The mediating
Foundational Belief Change
- Journal of Philosophical Logic
, 1992
"... : This paper is concerned with the construction of a base contraction (revision) operation such that the theory contraction (revision) operation generated by it will be fully AGM-rational. It is shown that the theory contraction operation generated by Fuhrmann's minimal base contraction operati ..."

(base) contraction so as to make it maxichoice. Descriptors: belief, change, contraction, revision, base, theory. We often change our beliefs. We learn new things, occasionally things that conflict with our current beliefs. On such occasions new beliefs replace the old ones. It is as if this process
Beliefs and Dispositions
"... ABSTRACT: This paper is about the dispositional difference that demonstrative and indexical beliefs make. More specifically, it is about the dispositional difference between my believing that NN is P (where I am NN) and my believing that I, myself, am P. Identifying a dispositional difference in thi ..."

that the dispositions associated with indexical beliefs are best of thought of as like belief revision policies: they make no difference to the content of our conception of the world, but they govern how we can change and revise that conception, and in so doing contribute to making rational action possible. Seeing all
Inverse Resolution as Belief Change
"... Belief change is concerned with modelling the way in which a rational reasoner maintains its beliefs as it acquires new information. Of particular interest is the way in which new beliefs are acquired and determined and old beliefs are retained or discarded. A parallel can be drawn to symbolic machi ..."

Semantic Belief Change

Central to any investigation of belief change is the notion of an epistemic state. This dissertation is mainly concerned with three issues involving epistemic states: 1. How ..."
