Except Tay learned a lot more, thanks in part to the trolls at 4chan’s /pol/ board.
Peter Lee, the vice president of Microsoft research, said on Friday that the company was “deeply sorry” for the “unintended offensive and hurtful tweets from Tay.”
In a blog post addressing the matter, Lee promised not to bring the bot back online until “we are confident we can better anticipate malicious intent that conflicts with our principles and values.”
Lee explained that Microsoft was hoping that Tay would replicate the success of XiaoIce, a Microsoft chatbot that’s already live in China. “Unfortunately, within the first 24 hours of coming online,” an emailed statement from a Microsoft representative said, “a coordinated attack by a subset of people exploited a vulnerability in Tay.”
Microsoft spent hours deleting Tay’s worst tweets, which included a call for genocide involving the n-word and an offensive term for Jewish people. Many of the really bad responses, as Business Insider notes, appear to be the result of an exploitation of Tay’s “repeat after me” function — and it appears that Tay was able to repeat pretty much anything.
“We stress-tested Tay under a variety of conditions, specifically to make interacting with Tay a positive experience,” Lee said in his blog post. He called the “vulnerability” that caused Tay to say what she did the result of a “critical oversight,” but did not specify what, exactly, it was that Microsoft overlooked.
Not all of Tay’s terrible responses were the result of the bot repeating anything on command. This one was deleted Thursday morning, while the Intersect was in the process of writing this post:
In response to a question on Twitter about whether Ricky Gervais is an atheist (the correct answer is “yes”), Tay told someone that “ricky gervais learned totalitarianism from adolf hitler, the inventor of atheism.” the tweet was spotted by several news outlets, including the Guardian, before it was deleted.
All of those efforts to get Tay to say certain things seemed to, at times, confuse the bot. In another conversation, Tay tweeted two completely different opinions about Caitlyn Jenner:
It appears that the team behind Tay — which includes an editorial staff — started taking some steps to bring Tay back to what it originally intended her to be, before she took a break from Twitter.
For instance, after a sustained effort by some to teach Tay that supporting the Gamergate controversy is a good thing:
Tay started sending one of a couple of almost identical replies in response to questions about it:
Zoe Quinn, a frequent target of Gamergate, posted a screenshot overnight of the bot tweeting an insult at her, prompted by another user. “Wow it only took them hours to ruin this bot for me,” she wrote in a series of tweets about Tay. “It’s 2016. If you’re not asking yourself ‘how could this be used to hurt someone’ in your design/engineering process, you’ve failed.”
Towards the end of her short excursion on Twitter, Tay started to sound more than a little frustrated by the whole thing:
Microsoft’s Lee, for his part, concluded his blog post with a few of the lessons his team has learned.
“AI systems feed off of both positive and negative interactions with people. In that sense, the challenges are just as much social as they are technical. We will do everything possible to limit technical exploits but also know we cannot fully predict all possible human interactive misuses without learning from mistakes…We will remain steadfast in our efforts to learn from this and other experiences as we work toward contributing to an Internet that represents the best, not the worst, of humanity.”
