1 00:00:00,100 --> 00:00:03,440 The recall, the cases where it's truly Bush, and 2 00:00:03,440 --> 00:00:08,680 we recognize it's Bush, is 123 over 127, which resolves to about .97, 97%. 3 00:00:08,680 --> 00:00:12,920 Where as the precision for George W. 4 00:00:12,920 --> 00:00:14,860 Bush, that's this column over here. 5 00:00:14,860 --> 00:00:17,480 In my calculations 123 over 156, 6 00:00:17,480 --> 00:00:21,700 which is the sum of all the predictions of George W. 7 00:00:21,700 --> 00:00:25,440 Bush. And that resolves to about 0.79. 8 00:00:25,440 --> 00:00:26,230 Much lower. 9 00:00:26,230 --> 00:00:28,470 Whether this warrants a recall for George W. 10 00:00:28,470 --> 00:00:31,700 Bush, is an open question, but he can see he has symmetry. 11 00:00:31,700 --> 00:00:35,130 This specific learning algorithm is really good in recalling or 12 00:00:35,130 --> 00:00:35,920 finding George W. 13 00:00:35,920 --> 00:00:38,630 Bush, provided that it's actually Bush in the image. 14 00:00:38,630 --> 00:00:40,990 But it mistakes many, many other people. 15 00:00:40,990 --> 00:00:44,170 Most notably Colin Powell and Donald Rumsfeld for George W. 16 00:00:44,170 --> 00:00:44,670 Bush.
