Exploring the Geometry and Topology of Neural Network Loss Landscapes

Stefan Horoi*, Jessie Huang*, Bastian Rieck, Guillaume Lajoie, Guy Wolf, Smita Krishnaswamy

Proceedings of the 20th Symposium on Intelligent Data Analysis (IDA), Springer’s LNCS vol. 13205, 2022

We presented a novel way of sampling the loss landscape of artificial neural networks and use manifold learning and computational homology to study the sampled data. We found that the extracted geometrical and topological features of the loss landscapes hold meaningful information about the model’s ability to generalize.
