Towards Comprehensive Foundations of Computational Intelligence

Abstract. Although computational intelligence (CI) covers a vast variety of different methods it still lacks an integrative theory. Several proposals for CI foundations are discussed: computing and cognition as compression, meta-learning as search in the space of data models, (dis)similarity based methods providing a framework for such meta-learning, and a more general approach based on chains of transformations. Many useful transformations that extract information from features are discussed. Heterogeneous adaptive systems are presented as particular example of transformation-based systems, and the goal of learning is redefined to facilitate creation of simpler data models. The need to understand data structures leads to techniques for logical and prototype-based rule extraction, and to generation of multiple alternative models, while the need to increase predictive power of adaptive models leads to committees of competent models. Learning from partial observations is a natural extension towards reasoning based on perceptions, and an approach to intuitive solving of such problems is presented. Throughout the paper neurocognitive inspirations are frequently used and are especially important in modeling of the higher cognitive functions. Promising directions such as liquid and laminar computing are identified and many open problems presented.

Les monnaies de fouille du monde grec (VIe-Ier s. a.C.)

Ce livre donne un état des récentes découvertes de monnaies de fouille en Méditerranée orientale dont celles faites en Égypte lors des fouilles sous-marines dans le delta du Nil en Égypte ou en Grèce sur les sites royaux de Macédoine. Une grande partie de ce matériel est inédite. L’ambition des auteurs est d’abord méthodologique : les monnaies de fouille sont des monnaies principalement perdues, souvent de faible valeur ou hors d’usage (décri, monnaies modifiées, fausses monnaies). L’objectif classique de leur étude est de fournir des marqueurs chronologiques aux archéologues, d’enrichir les corpus monétaires ou d’étudier la circulation. En réalité, elles offrent bien d’autres possibilités à la recherche (étude des phases de circulation et de décri, des pratiques monétaires, histoire économique, histoire des pratiques sociales, etc.), qu’elles soient trouvées en groupe ou isolées, dès lors qu’elles sont remises en contexte archéologique, de concert avec les autres artefacts, notamment céramiques

Coinage as commodity and bullion in the western Mediterranean, ca. 550–100 BCE

This article traces the effect of the entangled network of relations between the eastern and western Mediterranean on the introduction and development of coinage in the west. Particular focus is given to the role of Athenian owls and Corinthian-style pegasi within Sicily and Magna Graecia. Coinages from the eastern Mediterranean affected the type, form and fabric of coinage adopted by cities in the west, and formed a source of bullion for new coins. The significant number of Corinthian-style pegasi travelling to Sicily and Magna Graecia over a long period of time suggests that the presence of these coinages in the region should be linked to trade, and that eastern Greek coins were traded as a commodity for their silver content in exchange for grain and other goods. The legacy of Alexander the Great and then the gradual rise of Rome from the mid-third century BCE disturbed this network, but nonetheless it is likely that eastern coinages (now the issues of Hellenistic kings) continued to form a source of bullion for the west, which was increasingly controlled by Rome and Roman currency
