While most supervised machine learning models assume that training examples are sampled at random or adversarially, this article is concerned with models of learning from a cooperative teacher that selects “helpful” training examples. The number of training examples a learner needs for identifying a concept in a given class C of possible target concepts (sample complexity of C) is lower in mode...

The Internet is enhancing and challenging traditional approaches to teaching undergraduate neuroscience. In addition to the new FUN-supported development of a Society for Neuroscience Portal for higher education, there is a wealth of available teaching resources currently housed on the web. This article discusses the current state of digital libraries and introduces a series of exemplary web-ba...

It is our experience that many Web-based training (WBT) systems do not take into account the latest advancements in teaching or learning paradigms – they simply reflect Web technology. We believe that such a technical approach to building WBT systems has a number of drawbacks, since WBT systems are primarily about teaching and learning, rather than about technology. Thus, WBT systems should act...

Grid has been proposed to be a promising service-oriented platform for increasingly complex cooperative computing. The platforms of service-oriented Grids are often web-based where participants collaborate to achieve a common goal by sharing scarce Web-Based Computational/Computing Resources (WBCR). To effectively share the WBCR is a challenging problem in boundary-spanning grid environments, p...

Advance in technologies has revolutionized the traditional mode of teaching and learning. Various media authoring systems have been developed in order to enhance the effectiveness of learning and teaching processes by supplementing traditional teaching materials such as text books and lecture notes with interactive digital media. In this paper, we are going to discuss two media authoring system...

1 E-Mail: [email protected] Abstract Sophisticated Web-based courseware typically includes highly interactive elements like interactive illustrations or a virtual laboratory together with cooperative tools. The intention is to support active engagement with the teaching content and to educe intuitive understanding by experimentation. However, developing a greater pool of c...

We consider the use of cooperative caching to manage the memories of cluster-based servers. Over the last several years, a number of researchers have proposed locality-conscious servers that implement content-aware request distribution to address this problem [2, 17, 4, 5, 6]. During this development, it has become conventional wisdom that cooperative caching cannot match the performance of the...
