High confidence estimates of the mean of heavy-tailed real random variables
Olivier Catoni
We present new estimators of the mean of a real valued random variable, based on PAC-Bayesian iterative truncation. We analyze the non-asymptotic minimax properties of the deviatio…

Online Multi-task Learning with Hard Constraints
Gabor Lugosi, Omiros Papaspiliopoulos, Gilles Stoltz
We discuss multi-task online learning when a decision maker has to deal simultaneously with M tasks. The tasks are related, which is modeled by imposing that the M-tuple of actions…
