Adaptive Combination of Behaviors in an gent

Agents are of interest mainly when confronted with complex tasks. We propose a methodology for the automated design of such agents (in the framework of Markov Decision Processes) in the case where the global task can be decomposed into simpler -possibly concurrentsub-tasks. This is accomplished by automatically combining basic behaviors using Reinforcement Learning methods. The main idea is to ...

The Gent–McWilliams Skew Flux

This paper formulates tracer stirring arising from the Gent–McWilliams (GM) eddy-induced transport in terms of a skew-diffusive flux. A skew-diffusive tracer flux is directed normal to the tracer gradient, which is in contrast to a diffusive tracer flux directed down the tracer gradient. Analysis of the GM skew flux provides an understanding of the physical mechanisms prescribed by GM stirring,...

Virtual environments have a variety of uses, ranging from entertainment to simulation of hard-to-create environments for training and testing purposes. A common feature of virtual environments, especially those aimed at entertainment, is the presence of virtual entities we call agents, characters or objects in the virtual world possessing human characteristics and able to interact pro-actively ...

Conventional pharmacologic treatments for major depressive disorder (MDD) generally take several weeks to several months to have a clinically meaningful effect. This time lag to response constitutes a major burden for patients and contributes to increased morbidity and mortality. Two published studies in patients with MDD have now provided evidence for rapid and robust antidepressant efficacy o...
