Analogies and Theories: Formal Models of Reasoning

Analogies and Theories: Formal Models of Reasoning

I. GILBOA, L. SAMUELSON, D. SCHMEIDLER

Oxford University Press, Roumanie

2015



The book describes formal models of reasoning that are aimed at capturing the way that economic agents, and decision makers in general think about their environment and make predictions based on their past experience. The focus is on analogies (case-based reasoning) and general theories (rule-based reasoning), and on the interaction between them, as well as between them and Bayesian reasoning. A unified approach allows one to study the dynamics of inductive reasoning in terms of the mode of reasoning that is used to generate predictions

Alors que la guerre civile syrienne a franchi une étape lors du recul militaire américain, Washington se prépare à un désengagement d’Afghanistan sur fond de reprise de la violence en Irak.Tandis que les pays émergents connaissent un tassement économique et des difficultés sociales, l’Europe sort lentement de sa crise et les États-Unis, grâce au pétrole et au gaz de schiste, connaissent une réindustrialisation.En Asie, la Chine assied sa prééminence au moment où le Japon envisage de s’affranchir de l’article 9 de sa constitution et de redevenir une puissance globale.De l’Égypte à la Tunisie, les révolutions arabes connaissent une nouvelle physionomie pendant que le continent africain se trouve confronté à de multiples crises, du Mali à la RCA... tout en devenant un pôle de croissance que nul ne peut désormais ignorer

Case-Based Predictions: An Axiomatic Approach to Prediction, Classification and Statistical Learning

I. GILBOA, D. Schmeidler

World Scientific Publishers, Economic Theory Series

2012



This book presents an axiomatic approach to the problems of prediction, classification, and statistical learning. Using methodologies from axiomatic decision theory, and, in particular, the authors' case-based decision theory, the present studies attempt to ask what inductive conclusions can be derived from existing databases. It is shown that simple consistency rules lead to similarity-weighted aggregation, akin to kernel-based methods. It is suggested that the similarity function be estimated from the data. The incorporation of rule-based reasoning is discussed.

Inverse Problems and High- Dimensional Estimation ; Stats in the Château summer school, revised lectures (P. Alquier, E. Gautier et G. Stoltz, éditeurs)

The 'Stats in the Château' summer school was held at the CRC château on the campus of HEC Paris, Jouy-en-Josas, France, from August 31 to September 4, 2009. This event was organized jointly by faculty members of three French academic institutions ? ENSAE ParisTech, the Ecole Polytechnique ParisTech, and HEC Paris ? which cooperate through a scientific foundation devoted to the decision sciences.The scientific content of the summer school was conveyed in two courses, one by Laurent Cavalier (Université Aix-Marseille I) on "Ill-posed Inverse Problems", and one by Victor Chernozhukov (Massachusetts Institute of Technology) on "High-dimensional Estimation with Applications to Economics". Ten invited researchers also presented either reviews of the state of the art in the field or of applications, or original research contributions.This volume contains the lecture notes of the two courses. Original research articles and a survey complement these lecture notes. Applications to economics are discussed in various contributions.

La crise a complexifié l'échiquier international. En rompant avec la politique de son prédécesseur, le Président Obama a redonné une image à l'Amérique. Il lui reste à réussir le plus difficile : sortir son pays des conflits post-11 septembre.De la dynamique de l'Asie orientale à la nouvelle politique du Brésil, la sortie de crise accélère l'émergence d'un système multipolaire.Un monde « post-américain » serait-il en train de naître alors que s'ouvre la deuxième décennie du XXIe siècle ?
