In this paper, we study a variant of the framework of online learning using expert advice with limited/bandit feedback—we consider each expert a learning entity and thereby capture scenarios that are more realistic and practical for real-world applications. In our setting, the feedback at any time t is limited in a sense that it is only available to the expert i that has been selected by the ce...

The research group ”Computer Networks and Distributed Systems” of the “Institute of Computer Science and Applied Mathematics” at the University of Bern led by Prof. Dr. Torsten Braun focuses the research activities in the areas of mobile and multimedia communications as well as on distance learning and security architectures. In fall 2003, a Klausurtagung has been organized in Pochtenalp with t...

Natural images are often affected by random noise and image denoising has long been a central topic in Computer Vision. Many algorithms have been introduced to remove the noise from the natural images, such as Gaussian, Wiener filtering and wavelet thresholding. However, many of these algorithms remove the fine edges and make them blur. Recently, many promising denoising algorithms have been in...

Weighted logic programming, a generalization of bottom-up logic programming, is a successful framework for specifying dynamic programming algorithms. In this setting, proofs correspond to the algorithm’s output space, such as a path through a graph or a grammatical derivation, and are given a weighted score, often interpreted as a probability, that depends on the score of the base axioms used i...

Along with advancing mobile technologies and proliferating mobile devices and applications, mobile learning research has gained great momentum in recent years. While there have been review articles summarizing past research, studies identifying mobile learning research priorities based on experts’ latest insights have been lacking. This study employed the Delphi method to obtain a consensus fro...

The shuttle service in tourism depends on physical accessibility of a destination, on movement within the destination and the transport itself. In today’s world, transport is not just the act of getting to a wanted destination. Moreover, travelling by a certain vehicle can be a tourist attraction, if the transportation means is designed to arouse the feeling of joy and excitement. The purpose o...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...
