Bush Precision and Recall - Intro to Machine Learning

  • 0:00 - 0:03
    The recall, the cases where it's truly Bush, and
  • 0:03 - 0:09
    we recognize it's Bush, is 123 over 127, which resolves to about .97, 97%.
  • 0:09 - 0:13
    Where as the precision for George W.
  • 0:13 - 0:15
    Bush, that's this column over here.
  • 0:15 - 0:17
    In my calculations 123 over 156,
  • 0:17 - 0:22
    which is the sum of all the predictions of George W.
  • 0:22 - 0:25
    Bush. And that resolves to about 0.79.
  • 0:25 - 0:26
    Much lower.
  • 0:26 - 0:28
    Whether this warrants a recall for George W.
  • 0:28 - 0:32
    Bush, is an open question, but he can see he has symmetry.
  • 0:32 - 0:35
    This specific learning algorithm is really good in recalling or
  • 0:35 - 0:36
    finding George W.
  • 0:36 - 0:39
    Bush, provided that it's actually Bush in the image.
  • 0:39 - 0:41
    But it mistakes many, many other people.
  • 0:41 - 0:44
    Most notably Colin Powell and Donald Rumsfeld for George W.
  • 0:44 - 0:45
    Bush.
