Why algorithmic accountability is key. "Predictive policing" that was innaccurate & racist. https://www.propublica.org/article/machine-bias-risk-assessments-in-criminal-sentencing …pic.twitter.com/qpuUgKgicn
In this case, algorithms had benchmarks to check (re-offense rate) and we knew a variable to look for: race. Often, we have neither.
It's not just that algorithms aren't checked. We're using them in subjective decision-making systems where you *can't* check: no benchmark.
Gah. Facebook will stop using news sites to vet trending topics.That was the positive part. https://www.commerce.senate.gov/public/_cache/files/93a14e98-2443-4d27-bf04-1fc59b8cf2b4/22796A1389F52BE16D225F9A03FB53F8.facebook-letter.pdf …pic.twitter.com/GG5zfIyLUm
If I am reading their letter to Thune right, Facebook's response is to gut a perfectly defensible part of the process. Why? PR concerns atm.
We just learned there are two separate instances that Facebook acknowledges newsfeed algorithm smothered #Ferguson.pic.twitter.com/5SKan7Tu4y
The first, during Ferguson protests, was because the algorithm worked. Second, sometime after Dec. 2014, was "an error". What was the error?
Algorithmic forensics must be part of any accountability and reflection process. The trending topics brouhaha helped bring that discussion.
What else disappears into algorithmic spirals of silence? Links to acknowledged instances. https://www.commerce.senate.gov/public/_cache/files/93a14e98-2443-4d27-bf04-1fc59b8cf2b4/22796A1389F52BE16D225F9A03FB53F8.facebook-letter.pdf …http://time.com/3950525/facebook-news-feed-algorithm/ …
An example of algorithmic bias. Facebook switches algorithm to be video-friendly. News sites see engagement plummet. http://fortune.com/2016/05/30/facebook-video-engagement/ …

Consider it in light of this: More and more people get news on Facebook. We're talking about 1.5 billion here.https://twitter.com/knightfdn/status/737735462433886208 …
