Extending Gossip Algorithms to Distributed Estimation of U-Statistics
Igor Colin, Aurélien Bellet, Joseph Salmon +1
Efficient and robust algorithms for decentralized estimation in networks are essential to many distributed systems. Whereas distributed estimation of sample mean statistics has bee…
AUC Optimisation and Collaborative Filtering
Charanpal Dhanjal, Romaric Gaudel, Stephan Clemencon
In recommendation systems, one is interested in the ranking of the predicted items as opposed to other losses such as the mean squared error. Although a variety of ways to evaluate…
Sparsity in Multivariate Extremes with Applications to Anomaly Detection
Nicolas Goix, Anne Sabourin, Stéphan Clémençon
Capturing the dependence structure of multivariate extreme events is a major concern in many fields involving the management of risks stemming from multiple sources, e.g. portfolio…
On Anomaly Ranking and Excess-Mass Curves
Nicolas Goix, Anne Sabourin, Stéphan Clémençon
Learning how to rank multivariate unlabeled observations depending on their degree of abnormality/novelty is a crucial problem in a wide range of applications. In practice, it gene…
Scaling-up Empirical Risk Minimization: Optimization of Incomplete U-statistics
Stéphan Clémençon, Aurélien Bellet, Igor Colin
In a wide range of statistical learning problems such as ranking, clustering or metric learning among others, the risk is accurately estimated by -statistics of degree …
