Correction to: Nature Neuroscience https://doi.org/10.1038/s41593-021-00857-x, published online 13 May 2021.

In the version of this Article originally published, there was an error in Fig. 6c. In the graphs, the three smooth traces for “Test top-5 error (%),” now appearing on the left graph, initially appeared in the right graph, and the same reversal has been made for “Train top-5 error (%),” with the three jagged traces now appearing at the right.

The changes have been made to the online version of the article.
