Evolutionary algorithms (EAs) are merely blind search algorithms, which only make use of the relative fitness of solutions, but completely ignore the nature of the problem. Their performance can be improved by using new multirecombinative approaches, which provide a good…

The design of intelligent agents is a key issue for many applications. Although there is no universally accepted de nition of intelligence, a notion of rational agency has been proposed as an alternative for the characterization of intelligent agency.

This paper addresses the problem of recovering relative structure, in the form of an invariant, referred to as projective structure, from two views of a 3D scene. The invariant structure is computed without any prior knowledge of camera geometry, or…

This paper presents an adaptive learning model for market-making under the reinforcement learning framework. Reinforcement learning is a learning technique in which agents aim to maximize the long-term accumulated rewards. No knowledge of the market environment, such as the order…

Global discourse structures and local discourse relations are complementary modes of textual organization which an automated text generation system must account for and treat as interactive knowledge resources. To illustrate this interaction, we analyse a medical case report in terms…

To recognize a previously seen object, the visual system must overcome the variability in the object's appearance caused by factors such as illumination and pose. Developments in computer vision suggest that it may be possible to counter the influence of…

We identify different kinds of relevance relations between formulas that emerge in the process of belief revision. Informal definitions for alternative notions of relevance are suggested and a set of schemas and intuitive postulates for formalizing these notions are proposed.

Several surveys have indicated that many data warehouses fail to meet business objectives or are outright failures. One reason for this is that requirement engineering is typically overlooked in real projects. This paper addresses data warehouse design from a business…

The original Bio-Rad gene gun was unable to transfect acute or organotypic brain slices, as the amount of helium gas used, the distance for the gold-coated microcarriers to travel to target area were not optimised for fragile tissues, such as…

La noción de formularios como una manera de organizar y presentar datos ha sido usada desde el comienzo de la World Wide Web. Los formularios web han evolucionado junto con el desarrollo de nuevos lenguajes de marcado, en los cuales…
