Motivation / Abstract
The authors present an approach offer alternative directions for interpreting neural networks and discovering novel physical principles from the representations they learn. This is accomplished by applying symbolic regression to components of the learned model to extract explicit physical relations. This is also applied to a non-trivial cosmology example—a detailed dark matter simulation—and discover a new analytic formula which can predict the concentration of dark matter from the mass distribution of nearby cosmic structures.

What was discussed?
- What is symbolic regression?
- What does it mean for a DL model to have a separable internal structure?
- How do you deal with the curse of dimensionality?
