Thanks, Erik!
For those who want to jump to just the right spot:
- Aaron starts his presentation at 28m38s
- He talks about bad signals as part 2 of 3 at 42m02s, covering Italian "ha" and anonymous users
- He talks about anon specifically at 47m15s —and that section ends at about 55m, so it's only 8 minutes of video to watch (~4 minutes at 2x)
Some key things are the differences in robustness between the two types of models, and the testing by holding one feature constant to assess its global effect. Neat stuff.
