    Happy to share our new @DeepMindAI paper on AGILE, a method for training agents to follow language instructions by jointly learning a reward model from examples. No more template languages, or problems with hard/impossible to code reward functions! https://arxiv.org/abs/1806.01946

        Well, at least awesome enough to attract stellar interns like @DBahdanau, who did a very large chunk of this work. The co-authors all contributed greatly as well, of course 🙂

        is "Dealing with False Negatives" *the* point? :)

        Yes. Need to guard against degeneration present in other adversarial objectives (e.g. GANs etc), hence the buffer rejection method.

        nice work! been pondering on your recent convo w @LeonDerczynski re: fluidity vs double blind and wanted to ask: 1) do you expect this arxiv paper to be submitted for peer review? where? 2) does @deepmindai incentiviize / reward publication? arxiv == conf == journal or ?

        1) Most/all of our papers are submitted to peer reviewed conferences and/or journals. 2) Researchers are incentivised to produce good and impactful research, but there is no one metric for measuring this. It certainly does not boil down to number of papers, citations, etc.
