Active learning [1] is a branch of Machine Learning in which the learning algorithm, instead of being directly provided with pairs of problem instances and their solutions (their l...
Many high-profile applications pose high-dimensional nearest-neighbor search problems. Yet, it still remains difficult to achieve fast query times for state-of-the-art approache...
Abstract. In this work we propose an alternative approach to inference in DLLite, based on a reduction to reasoning in an extension of function-free Horn Logic (EHL). We develop a ...
XGR (XML Data Grid) and BabelPeers are both data management systems based on distributed hash tables (DHT) that use the Pastry DHT to store data and meta data. XGR is based on the...
We propose a directed graphical representation of utility functions, called UCP-networks, that combines aspects of two existing preference models: generalized additive models and ...
