    31. pro 2019.

    To end 2019, I want to express thanks for all the great people I've worked with this year. Naturally, this is an opportunity to brag a little, but all this work is due thanks to leadership/effort from fantastic interns, collaborators, etc, so hopefully you will indulge me (1/16)

    Registering to vote from abroad has never been easier for Americans. Took me a couple of minutes, with no printing/scanning/faffing. Register to vote today, so that we can regain control of our democracy and its institutions!

    I for one am amazed that a Tory party who won’t publish a report showing they took £3.5m in donations from Russians and that Russia interfered in the referendum also won’t publish any economic assessment of their WTO plan which would absolutely devastate the economy.

    Why is anyone surprised? The is staffed by small-minded wannabe fascists lead by actual traitor . Elections have consequences, and the consequence here is to further turn the UK into a shithole, unless the Tory tide is reversed.

    It's not OK to claim that a system has "near-human abilities" while just releasing a few handpicked examples. We fully release "very-far-from-human abilities" systems every month. If your system is "near-human" it can certainly be shared.

    Pause for a second. Every newspaper has bias. That’s OK. But this I think is a 1st. A national broadsheet newspaper knowingly publishes, as its front page banner headline, an outright deliberate 100% lie. When you reach this point - one has to wonder how democracy can survive.

    Fooling a human once thing. Producing a chatbot that doesn't have a systematic and recognisable "flavour" (ugh) is another. We typically get frustrated by lack of ability to act in a goal-oriented conv, but in open dialogue I feel the "uncanny valley" lies elsewhere... (6/6)

    But if we *must* do human testing, I feel like seeing whether humans can discriminate between chatbot and human interlocutors, if they get several "episodes" and get to know the result of each episode before the next is a fairer way to do it. (5/6)

    Third, from research perspective, I don't think "turing test" style eval resolves anything, although it's better than any automated metric. Even then, results are sensitive to parameters of test, and people will optimize against a particular version when designing systems. (4/6)

    Second the topic: non-goal oriented chatbots is just language modelling where inter-utterance consistency particularly matters. I'm not seeing that much inter-utterance consistency in the form of "memory" here, just decent on-topic consistency. Hard to get that excited. (3/6)

    There's so much not to like. First, the "discovery" that minimising perplexity allows you to train a language model. We've been minimising NLL, typically div'd by number of tokens, for LM objectives, for at least a decade. Minimising either is equiv to minimising PPL. (2/6)

    Googler asks a good question here, so I'll share my thoughts on Meena in a short thread. (1/6)

    Except for a few Lexiters who think the workers will be revolutionised by a crash in their standard of living, you failed the people you were supposed to represent. A period of reflection, humility and listening from you and your supporters would not go amiss at this moment.

    I know Brexiters get angry when we imply that they’re all a bit thick, and obviously the VAST majority of Brexiters are highly intelligent and it’s just an unfortunate coincidence that ALL the Brexiters we ever hear speak or read tweets from ARE a bit thick.

    It would be a shame if this video that exposes Mitch McConnell got tons of retweets and moved from 890,000 views to 1 Million views by tomorrow.

    11.05 No sound in my brexity town. Am drinking French wine and pate. I have spent today being terribly sad. Tomorrow I will become angry. I will not forgive or forget. I will not come together to make The UK great but I will work to get Johnson OUT. Brexiters rot in hell.

    I forced another vote to subpoena John Bolton. But Senate Republicans voted for a cover-up and a sham trial.

    When Leavers say "let's come together" they mean "take some of the responsibility for the mess I've created". Brexit was, no matter how you look at it, a mean-spirited vote. There is no obligation for anybody to unite under those circumstances.
