    Loved it. I have your book in audio format, but I have to have it in dead tree form so I can re-read it.

    Great work!! Posted link to talk. As you said people need to take political action to enforce transparency and accountability for those who create and implement these algorithms.

    I read your book and loved it. Your talk is basically a 15 minute version of your book, but nevertheless I love it.

    However, I am nervous about the “orchestra curtain” example you discussed. This needs to be handled with care. Omitting information like race or sex from a data set will not necessarily lead to a trained model that is color-blind or gender-neutral. These variables are likely to be correlated to other variables in the data set, and the algorithm may learn to use those other variables as a proxy for the missing variable, and thus learn to discriminate anyway (for example, the algorithm has no access to race data but since zip code is correlated with race that algorithm learns to racially discriminate by using zip codes).

    A better approach would be to include variables such as sex or race when training a model so that you can remove their effects from other variables. But when the time comes to make predictions with the model, feed it false data; tell it that every applicant is white or male. This algorithm would in effect be less discriminatory than one that did not include this information when trained.

      You’ve given an excellent reminder, ntGuardian. Simply omitting data doesn’t make algorithms any smarter. In fact, simply blaming algorithms misses the point that it’s better to optimize in new directions and in a clear eyed way. The training suggestion you mention, testing with false data, is more towards the benefit of a double-blind experiment, and less towards a color-blind (eyes closed head in the sand) approach.

      I had a different take on the orchestra curtain example because she qualified it using the phrase ‘not distracted’ and ‘what’s important ‘

      In pre-WW2 a German General is quoted as describing his generals ranks as having 2 traits
      from the list clever, lazy, stupid, industrious

      The clever lazy generals were said to be the best because they were not distracted and could focus on what was important

    Outstanding presentation. This is important work you’re doing, especially so as I know of no one else doing it. Glad to see you doing it so well.
    I hope everyone will “like” and share this talk; it’s relevant and important to every one of us.

    Wonderful TED talk and so timely. I do a significant amount of data analysis as part of my job so I have an ‘above average’ appreciation for your message. In the natural world, mutation is central to evolution. Algorithms reject mutations, either as errors or outliers, so Big Data, in my opinion, will eventually lead to stagnation in so many ways. The hubris around ‘Big Data’ has been painful to observe.

    Thank you for a very informative talk. “Blind” being the operative word. Agree that big data need to be held accountable by transparency and by people being informed enough to demand understanding of the algorithm.

    Reblogged this on Opportunities And Ideas For Home Business and commented:
    After listening to Cathy O’Neil On Ted Talks the topic being “The Era Of Blind Faith In Big Data Must End,” It does give food for thought, and requires another look at how data is acquired and used. Looking at it from her perspective the use of data collected is not without bias, unintentionally or otherwise and needs to be looked at more closely for integrity checks.

    Reblogged this on The Curious Scribbler and commented:
    Algorithms reflect the human biases of their designers. This matters because algorithms may decide what kind of credit card you can apply for or whether you get a job interview. Thank you Cathy O’Neil for unpacking the black box.

      If you watch it on the TED site, you can either watch the video with closed captions, or you can read the transcript. It’s worth a read!
