Coordination failure, or agents’ uncertainty about the action of other agents, may be an important source of congestion in large decentralized systems. The El Far01 or Santa Fe bar problem provides a simple paradigm for congestion and coordination problems that may arise with over utilization of the Internet. This paper recasts the problem in a stochastic framework and derives a simple adaptive...

A recent paper (Beaver, 2004) recasts the Centering algorithm for pronoun resolution (Brennan et al., 1987) in terms of optimality theory (OT). Although the limitations of centering for pronoun resolution are well known, the algorithm's restatement in OT highlights the strengths of centering and produces an algorithm whose behavior is more transparent to the developer. The authors' motivation f...

We present a perfect sampling algorithm that can be applied to the master equation of gene regulatory networks. The method recasts Gillespie's stochastic simulation algorithm (SSA) in the light of Markov chain Monte Carlo methods and combines it with the dominated coupling from the past (DCFTP) algorithm to provide guaranteed sampling from the stationary distribution. We show how the DCFTP-SSA ...

This paper will focus on recent changes in the relationships between the public and the private sector within the health assistance network, by analyzing selected information on health services and on legal rules related to supporting the private assistance subsystem. This approach recasts analyses which articulate the simultaneous examination of both the material and political instances that p...

Bohannon and Stanowicz (1988) have claimed that contrary to popular belief, children do receive negative evidence about the ungrammaticality of their utterances in the form of recasts, expansions, and repetitions. Bohannon and Stanowicz argue that given such negative evidence, learnability theory shows that natural languages can be learned and that there is no need to postulate innate knowledge...

Purpose—We sought to confirm predictions based on past findings that pre-treatment mean length of utterance (MLU) would predict which of two grammatical treatments would best facilitate generalized and maintained grammatical development in preschoolers with specific language impairment (SLI). Method—The participants were 57 preschoolers with specific language impairment (SLI). A randomized grou...

In w this paper we characterize a feature superset for Collaborative Virtual Reality Environments (CVRE), and derive a component framework to transform stand-alone VR navigators into full-fledged multithreaded collaborative environments. The contributions of our approach rely on a cost-effective and extensible technique for loading software components into separate POSIX threads for rendering, ...

Program understanding is the process of acquiring knowledge from a computer program. Although research work utilising knowledge engineering techniques has been undertaken in this field, it is our observation that a thorough application of AI methodology has not been sufficiently explored. In this paper, we present a clarity guided belief revision approach to domain knowledge recovery in legacy ...

Two challenges lie in the facial attractiveness computation research: the lack of true attractiveness labels (scores), and the lack of an accurate face representation. In order to address the first challenge, this paper recasts facial attractiveness computation as a label distribution learning (LDL) problem rather than a traditional single-label supervised learning task. In this way, the negati...

A bstract Motivated by the goal of understanding quantum systems away from maximal chaos, in this note we derive a simple closed form expression for fermion four point function large q SYK model valid at arbitrary temperatures and to leading order 1/ N . The result captures both temperature, weakly coupled regime, low nearly conformal, maximally chaotic regime model. derivation proceeds Sommerf...
