How do models learn: understanding feature importance in deep neural networks?

Description

How can we explain how deep neural networks arrive at decisions? Feature representation is complex and to the human eye opaque; instead a set of interpretability tools intuit what the model has learned by looking at what inputs it pays attention to. This talk will introduce some of the challenges associated with interpretability for deep neural networks and discuss desirable properties methods should fulfill in order to build trust between humans and algorithms.
