Pre-probabilistic sophistication

by Osamu Kada , 2009
"... We consider pre-probabilistic sophistication where an agent’s two-consequence act is based on a probabilistic belief over a finite λ-system of events. We identify the likelihood relation on the events such that if an agent is pre-probabilistically sophisticated, then its probability measure must rep ..."

Probabilistic Sophistication and Reverse Bayesianism

by Edi Karni, Marie-louise Vierø , 2013
"... This paper extends our earlier work on reverse Bayesianism by relaxing the assumption that decision makers abide by expected utility theory, assuming instead weaker axioms that merely imply that they are probabilistically sophisticated. We show that our main results, namely, (modified) representatio ..."

Event exchangeability: Probabilistic sophistication without continuity or monotonicity

by Soo Hong, Jacob, S. Sagi - Econometrica , 2006
"... Building on the Ramsey–de Finetti idea of event exchangeability, we derive a char-acterization of probabilistic sophistication without requiring any of the various versions of monotonicity, continuity, or comparative likelihood assumptions imposed by Savage (1954), Machina and Schmeidler (1992), and ..."

Practical network support for IP traceback

by Stefan Savage, David Wetherall, Anna Karlin, Tom Anderson , 2000
"... This paper describes a technique for tracing anonymous packet flooding attacks in the Internet back towards their source. This work is motivated by the increased frequency and sophistication of denial-of-service attacks and by the difficulty in tracing packets with incorrect, or “spoofed”, source ad ..."

The INQUERY Retrieval System

by James Callan, W. Bruce Croft, Stephen M. Harding - In Proceedings of the Third International Conference on Database and Expert Systems Applications
"... As larger and more heterogeneous text databases become available, information retrieval research will depend on the development of powerful, efficient and flexible retrieval engines. In this paper, we describe a retrieval system (INQUERY) that is based on a probabilistic retrieval model and provides ..."

Sophisticated Indexes for Implementing Probabilistic Expert Systems

by C. J. Butz, F. Fang
"... Abstract. Indexes are crucial for the efficient implementation of probabilistic expert systems. However, the indexes previously proposed, and the methods for applying them, are somewhat elementary. Moreover, recent experiments involving large Bayesian networks have resulted in the computer running o ..."

In this paper, we propose several sophisticated index structures for implementing probabilistic expert systems. We show the advantages of these advanced indexes over the previously

Probabilistic models of language processing and acquisition

by Nick Chater , Christopher D Manning - Trends in Cognitive Science , 2006
"... Probabilistic methods are providing new explanatory approaches to fundamental cognitive science questions of how humans structure, process and acquire language. This review examines probabilistic models defined over traditional symbolic structures. Language comprehension and production involve prob ..."

probabilistic inference in such models; and acquisition involves choosing the best model, given innate constraints and linguistic and other input. Probabilistic models can account for the learning and processing of language, while maintaining the sophistication of symbolic models. A recent burgeoning
