+This problem was first introduced by [Franceschi et al. (2017)](https://arxiv.org/abs/1703.01785).
 In this problem, the data is the MNIST dataset.
 The training set has been corrupted: with a probability $p$, the label of the image $`y\in\{1,\dots,10\}`$ is replaced by another random label between 1 and 10.
 We do not know beforehand which data has been corrupted.
