Collaborative recommender systems allow personalization for e-commerce by exploiting similarities and dissimilarities among customers' preferences. We investigate the use of association rule mining as an underlying technology for collaborative recommender systems. Association rules have been used with success in other domains.

This thesis provides a novel approach to using data mining for e-commerce. The focus of our work is to apply association rule mining to collaborative recommender systems, which recommend articles to a user on the basis of other users' ratings for these articles as well as the similarities between this user's and other users' tastes. In this work, we propose(More)
In this paper we propose a new approach for mining association rules of classiication type particularly suited for use in collaborative recommender systems. Such systems rely on information about relationships between diierent users' preferences in order to recommend items of potential interest to the target user. Despite their successful application to(More)
—In this paper, we propose a novel design of compliant safe joint, which has flexibility when the work load exceeds a pre-defined threshold. The compliance is generated by a spring. We design a special transmission mechanism to convert axial motion into circumferential motion such that the linear compliance can be converted into circular one. When the(More)
— Nowadays, robotic systems make use of compliant joint actuation to provide safe human-robot physical interactions, and in general, to improve the friendliness of the mechanism. However, note that with the introduction of these passive flexible elements, the actuators (which input the control actions) can not explicitly set the driving torque of the(More)
