As someone going into the field, can you explain what this means? Specifically, I'd assume we're trying to isolate some outliers that are causing a funky bias in the learner. In what way would you automate their discovery (what does it mean to "discover" the outliers in this scenario?)? Just looking for clarification because I feel like I should know this. Trying to couch the problem in terms I'm more familiar with.
