    A Survey Of Methods For Explaining Black Box Models

    In the last years many accurate decision support systems have been constructed as black boxes, that is as systems that hide their internal logic to the user. This lack of explanation constitutes both a practical and an ethical issue. The literature reports many approaches aimed at overcoming this crucial weakness sometimes at the cost of scarifying accuracy for interpretability. The applications in which black box decision systems can be used are various, and each approach is typically developed to provide a solution for a specific problem and, as a consequence, delineating explicitly or implicitly its own definition of interpretability and explanation. The aim of this paper is to provide a classification of the main problems addressed in the literature with respect to the notion of explanation and the type of black box system. Given a problem definition, a black box type, and a desired explanation this survey should help the researcher to find the proposals more useful for his own work. The proposed classification of approaches to open black box models should also be useful for putting the many research open questions in perspective.Comment: This work is currently under review on an international journa

    Advances in Robotics, Automation and Control

    The book presents an excellent overview of the recent developments in the different areas of Robotics, Automation and Control. Through its 24 chapters, this book presents topics related to control and robot design; it also introduces new mathematical tools and techniques devoted to improve the system modeling and control. An important point is the use of rational agents and heuristic techniques to cope with the computational complexity required for controlling complex systems. Through this book, we also find navigation and vision algorithms, automatic handwritten comprehension and speech recognition systems that will be included in the next generation of productive systems developed by man

    Ubiquitous User Modeling

    More and more interactions take place between humans and mobile or connected IT-systems in daily life. This offers a great opportunity, especially to user modeling, to reach better adaptation with ongoing evaluation of user behavior. This work develops a complete framework to realize the newly defined concept of ubiquitous user modeling. The developed tools cover methods for the uniform exchange and the semantic integration of partial user models. They also account for the extended needs for privacy and the right of every human for introspection and control of their collected data. The SITUATIONALSTATEMENTS and the exchange language USERML have been developed on the syntactical level, while the general user model ontology GUMO and the UBISWORLD ontology have been developed on the semantical level. A multilevel conflict resolution method, which handles the problem of contradictory statements, has been implemented together with a web-based user model service, such that the road capability and the scalability can be proven with this approach.Immer häufiger auftretende Interaktionen im täglichen Leben zwischen Menschen und vernetzten oder mobilen IT-Systemen bieten insbesondere für die Benutzermodellierung eine große Chance, durch ständige Evaluation des Benutzerverhaltens verbesserte Adaptionsleistungen zu erzielen. Die vorliegende Arbeit entwickelt ein komplettes Rahmensystem, um dieses neu definierte Konzept der ubiquitären Benutzermodellierung zu realisieren. Die erarbeiteten Werkzeuge umfassen Methoden zum einheitlichen Austausch und zur semantischen Integration von partiellen Benutzermodellen. Sie berücksichtigen aber auch die erhöhten Anforderungen an die Privatsphäre, sowie das Recht der Menschen auf Introspektion und Kontrolle über die erhobenen Daten. Auf syntaktischer Ebene werden die situationsbeschreibenden Aussagen sowie die Austauschsprache UserML entworfen. Auf semantischer Ebene werden die allgemeine Benutzermodell-Ontologie GUMO und die UBISWELT-Ontologie entwickelt. Ein mehrstufiger Konfliktlösungsmechanismus, der das Problem sich widersprechender Aussagen bearbeitet, wird zusammen mit einem webbasierten Benutzermodell-Service implementiert, sodass die Praxistauglichkeit und die Skalierbarkeit dieses Ansatzes an mehreren Beispielen gezeigt werden kann

    Shut Up and Take My Money: Engaging Facebook Communities to Build the Brand Narrative

    Full text link
    Social media is revolutionizing the way firms manage their brands. A broad variety of platforms provide businesses an opportunity to engage in bidirectional dialogue with their customers, the effect of which is to enhance the brand/consumer relationship. This paper contends that virtual brand communities of the type that form through social media have an important role to play in the development of a brand’s personality. Using a case study approach we demonstrate how one firm has adopted Facebook to provide their brand community with a voice which contributes to the development of the brand narrative. We find that by using well-crafted content the firm elicits the support of their community and that this interaction contributes to the development of the brand ethos
