Collapse Button Quick Abstract
Man vs. machine competitions have always been attracting much public attention and the famous defeats of human champions in chess, Jeopardy!, Go or poker undoubtedly mark important milestones in the history of artificial intelligence. In this article we reflect on our experiences with a game-centric approach to teaching artificial intelligence that follows the historical development of algorithms by popping the hood of these champion bots. Moreover, we made available a server infrastructure for playing card games in perfect information and imperfect information playing mode, where students can evaluate their implementations of increasingly sophisticated game-playing algorithms in weekly online competitions, i.e. from rule-based systems to exhaustive and heuristic search in game trees to deep learning enhanced Monte Carlo methods and reinforcement learning completely freed of human domain knowledge. The evaluation of this particular course setting revealed enthusiastic feedback not only from students but also from the university authority. What started as an experiment became part of the standard computer science curriculum after just one implementation.

Collapse Button Quick Abstract
Hand eczema is one of the most frequent skin diseases affecting up to 14% of the population. Early detection and continuous observation of eczemas allows for efficient treatment and can therefore relieve symptoms. However, purely manual skin control is tedious and often error prone. Thus, an automatic approach that can assist the dermatologist with his work is desirable. Together with our industry partner swiss4ward, we devised an image processing method for hand eczema segmentation based on support vector machines and conducted several experiments with different feature sets. Our implementation is planned to be integrated into a clinical information system for operational use at University Hospital Zurich. Instead of focusing on a high accuracy like most existing state-of-the-art approaches, we selected F1 score as our primary measure. This decision had several implications regarding the design of our segmentation method, since all popular implementations of support vector machines aim for optimizing accuracy. Finally, we evaluated our system and achieved an F1 score of 58.6% for front sides of hands and 43.8% for back sides, which outperforms several state-of-the-art methods that were tested on our gold standard data set as well.

Skyline Computation on Commercial Data

Topics: Industrial Applications of AI; Data Science

Collapse Button Quick Abstract
Many different skyline algorithms for preference-based search have been proposed and compared in the literature, but most of these evaluations were based on synthetic data. In this paper, we present a case study of skyline computation on commercial data that we consider representative for many e-commerce platforms. The results of our measurements differ significantly from the results reported on synthetic data.

SECURING ACCESS TO EMBEDDED SYSTEMS - An Effective Concept for Devices Lacking Internet Connection

Topics: Accessibility Issues and Technology; Usability and Ergonomics; Authentication and Access Control; Web Security and Privacy

Authors: Bruno Juchli , Peter Sollberger and Roland Portmann

Affiliation: Lucerne University of Applied Sciences & Arts, Switzerland

Digital Object Identifier: 10.5220/0002779401520158

Proceedings of WEBIST 2010, ISBN: 978-989-674-025-2

Collapse Button Quick Abstract
Many embedded systems provide a web interface for maintenance tasks such as system configuration, test execution and firmware updating. Access to this interface usually needs to be restricted to authorized employees. This paper shows an efficient and cost-effective concept to secure maintenance interfaces using widespread standards and technology. By storing authorisation information in standard compliant X.509 certificate extensions Transport Layer Security (TLS) and X.509 Public Key Infrastructure (PKI) provide mutual authentication, message integrity as well as confidentiality and enable authorisation of employees. Practical experience of the implementation completes this paper.
