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 ..."

The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

is determined by computing its expected (under the risk-neutral measure) future cash flows discounted at the risk-free rate. As the credit spread CS(t) is uniquely defined through: (1) the price of a debt claim, (2) this debt claim's contractual cash flows, and (3) the (appropriate) risk-free rate, we can
Developments in the Measurement of Subjective Well-Being

"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

of others and depart from the standard model of the rational economic agent in other ways. If people display bounded rationality when it comes to maximizing utility, then their choices do not necessarily reflect their "true" preferences, and an exclusive reliance on choices to infer what people
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

We know that the same animal will salivate also when it hears a bell that has repeatedly sounded a few seconds before the sausage appears, as if the bell induced the well-known, pleasant anticipation of the desired sausage.

Automatic program repair with evolutionary computation,”
- Commun. ACM,
, 2010
"... Abstract There are many methods for detecting and mitigating software errors but few generic methods for automatically repairing errors once they are discovered. This paper highlights recent work combining program analysis methods with evolutionary computation to automatically repair bugs in off-th ..."

We then use structural differencing 1 and delta debugging 25 techniques to minimize the size of the repair, providing a compact human-readable patch. A significant impediment for an evolutionary algorithm like
Is dispersal neutral
- Trends Ecol. Evol
, 2014
"... Dispersal is difficult to quantify and often treated as purely stochastic and extrinsically controlled. Consequently, there remains uncertainty about how individual traits mediate dispersal and its ecological effects. Addressing this uncertainty is crucial for distinguishing neutral versus non-neut ..."

Dispersal (see Glossary) is a fundamental process in population biology, ecology, and evolution Darwin Many areas of ecology and evolutionary biology would benefit from better empirical understanding of the adaptive drivers of dispersal traits
Finding Needles in Haystacks Is Not Hard with Neutrality
- Proceedings of the 5th European Conference on Genetic Programming. Springer LNCS 2278
, 2002
"... Abstract. We propose building neutral networks in needle-in-haystack fitness landscapes to assist an evolutionary algorithm to perform search. The experimental results on four different problems show that this approach improves the search success rates in most cases. In situations where neutral netw ..."

Evolutionary Algorithms and the Problem-Specific Knowledge

The discussion is based on example of path-planning and navigation problems; we have also used Evolutionary Planner/Navigator for var ..."

A dynamic model of social network formation.
- Proc. Nat. Acad. Sci. U.S.A.

"... We consider a dynamic social network model in which agents play repeated games in pairings determined by a stochastically evolving social network. Individual agents begin to interact at random, with the interactions modeled as games. The game payoffs determine which interactions are reinforced, and ..."

treatments of evolutionary game dynamics 1 2 operate entirely in this paradigm. This is due, to a large extent, to considerations of theoretical tractability of the model. Models have been introduced that allow the agents some control over their choice of partner (3), but the control is still exerted in a
