WEBVTT 00:00:00.100 --> 00:00:03.440 The recall, the cases when it's truly Bush, and 00:00:03.440 --> 00:00:08.680 we recognize it's Bush, is 123 over 127, which resolves to about .97, 97%. 00:00:08.680 --> 00:00:12.920 Where as the precision for George W. 00:00:12.920 --> 00:00:14.860 Bush, that's this column over here. 00:00:14.860 --> 00:00:17.480 In my calculations 123 over 156, 00:00:17.480 --> 00:00:21.700 which is the sum of all the predictions of George W. 00:00:21.700 --> 00:00:25.440 Bush. And that resolves to about 0.79. 00:00:25.440 --> 00:00:26.230 Much lower. 00:00:26.230 --> 00:00:28.470 Whether this warrants a recall for George W. 00:00:28.470 --> 00:00:31.700 Bush, is an open question, but you can see the asymmetry. 00:00:31.700 --> 00:00:35.130 This specific learning algorithm is really good in recalling or 00:00:35.130 --> 00:00:35.920 finding George W. 00:00:35.920 --> 00:00:38.630 Bush, provided that it's actually Bush in the image. 00:00:38.630 --> 00:00:40.990 But it mistakes many, many other people. 00:00:40.990 --> 00:00:44.170 Most notably Colin Powell and Donald Rumsfeld for George W. 00:00:44.170 --> 00:00:44.670 Bush.
