At the end of the talk I stood up and made the comment that it was obvious that the picture with the tanks was made on a sunny day while the other picture (of the same field without the tanks) was made on a cloudy day.  I suggested that the \"neural net\" had merely trained itself to recognize the difference between a bright picture and a dim picture.\"", "timestamp": "1454272597"}, {"author": "Jeff&nbsp;Kaufman", "source_link": "https://www.facebook.com/jefftk/posts/763507462802?comment_id=10100104306934902", "anchor": "fb-10100104306934902", "service": "fb", "text": "This post was referenced in https://www.nature.com/articles/d41586-019-02307-y", "timestamp": "1564582512"}]}
