Invited talk: Rajesh Ranganath - Have we learned to explain?

Interpretability enriches what can be gleaned from a good predictive model. Techniques that learn-to-explain have arisen because they require only a single evaluation of a model to provide an interpretation. I will discuss a flaw with several methods that learn-to-explain: the optimal explainer makes the prediction rather than highlighting the inputs that are useful for prediction, and I will discuss how to correct this flaw. Along the way, I will develop evaluations grounded in the data and convey why interpretability techniques need to be quantitatively evaluated before their use.
