i think you mean “deep learning” there ? back-propagation existed way before that.

  I didn't say he invented it, and for some reason I see lots of comments wanting to nitpick over the details of his contributions. I'll just copy the relevant sentence from his Wikipedia article, which I think is a very fair assessment: > With David Rumelhart and Ronald J. Williams, Hinton was co-author of a highly cited paper published in 1986 that popularised the backpropagation algorithm for training multi-layer neural networks, although they were not the first to propose the approach.
