For deep space networks, the major challenge is that transmission power consumption is serious while the power resource is limited. In this paper, we proposed a Temporal Graph Model based Power Aware Routing algorithm using a weighted metric of remaining power level, data rate and distance of nodes for determining routes. The traditional standards and techniques of static networks is hard to solve...
Peer review has long been used in education to provide students more timely feedback and allow them to learn from each other's work. In large courses and MOOCs, there is also interest in having students determine, or help determine, their classmates' grades. This requires a way to tell which peer reviewers' scores are credible. This can be done by comparing scores assigned by different reviewers with...
Two major challenges in collaborative filtering are the efficiency of the algorithms and the quality of the recommendations. A variety of machine learning methods have been applied to address these two issues, including feature selection, instance selection, and clustering. Most existing methods either compromise computational complexity or prediction precision. Two novel, scalable memory-based CF...
