This desperately needs a "What is BERT" section. I've been reading for 5 minutes, skimming for 10, and I'm still not sure.<p>Edit: OK, now I've clicked the correct random link and got the earlier paper: <a href="https://arxiv.org/pdf/1810.04805.pdf" rel="nofollow">https://arxiv.org/pdf/1810.04805.pdf</a><p>BERT is a "new language representation model".<p>People, when you write papers, give your readers a chance to come up to speed - a list of links to previous reading is essential. Make it prominent, and early.
