Abstract. The performance of an information retrieval system is usually measured in terms of two different criteria, precision and recall. This way, the optimization of any of its...
This paper proposes a novel anomaly detection system for spacecrafts based on data mining techniques. It constructs a nonlinear probabilistic model w.r.t. behavior of a spacecraft ...
We describe a Web-based interactive system, called PILOT, for testing computer science concepts. The strengths of PILOT are its universal access and platform independence, its use...
