Fast rates for prediction with costly or limited expert advice | Prof. Gilles Blanchard, Université Paris Saclay
We consider the problem of prediction with the help of experts: given a finite family of experts, or predictors, for forecasting a target variable of interest, we consider the problem of minimizing the [...] round and use at least two experts for prediction, for the "fast rate" of order 1/N to be achievable. Given time, we will also discuss a similar question in the setting of individual sequence prediction, the
