“The only reason a small company like you.com can compete with a large company like Google is because of the progress we’ve seen in AI. In particular, when it comes to so-called unsupervised and transfer learning. The idea here is that you can train very large neural networks on unsupervised text – basically all of Wikipedia, Common Crawl, and as much web text as you can find, while keeping in mind that not everything on the web is great in terms of training AI.”
