Summary
Why machine learning?
The statistical problem is only a proxy Example: detection of the action giving a phone call
A conjecture about adversarial features
Spurious correlations
Past observations
Nature does not shuffle the data. We do!
Multiple environments
Negative mixtures matter! Consider a search engine query classification problem
