Research Type Theoretical We investigate the problem of minimizing the excess generalization error... we show that if we are allowed to see the advice of only one expert per round... the worst-case excess risk is Ω(1/T) ... However, if we are allowed to see at least two actively chosen expert advices per training round... the fast rate O(1/T) can be achieved. We design novel algorithms achieving this rate in this setting, and in the setting where the learner has a budget constraint on the total number of observed expert advices, and give precise instance-dependent bounds on the number of training rounds and queries needed to achieve a given generalization error precision.
