Multi-class classification in nonparametric active learning

Boris Ndjia Njike, Xavier Siebert
2022 International Conference on Artificial Intelligence and Statistics  
Several works have recently focused on nonparametric active learning, especially in the binary classification setting under Hölder smoothness assumptions on the regression function.  ...  In this paper, we extend these results to multiclass classification under a more general smoothness assumption, which takes into account a broader class of underlying distributions.  ...  Multi-class classification in nonparametric active learning Then, there exists an event A 4 , such that P (A 4 ) ≥ 1 − δ/8 and (49) holds on A 4 . Thus we can easily conclude the first part. 2.  ...
