What is it about?
This work focuses on a method to simplify complex physical systems, like molecules. The framework helps researchers find important patterns in the behavior of these systems through neural networks. More importantly, the framework employs topology data analysis tools to provide interpretations of the neural networks, which are usually considered as a black box.
