Correction to: Nature Machine Intelligence https://doi.org/10.1038/s42256-020-0152-y, published online 14 February 2020.

In the version of this Article originally published, the placeholder text ‘Please add some text here’ after the section heading ‘Experiments’ was mistakenly not updated; this text should have read ‘In this section, we will introduce the employed datasets and experiments to indicate the performance of our DrugVQA model’. This has now been corrected.
