## Summary

Dr. Katie Schumann of the University of Tennessee explains her work evolving highly recurrent, sparse spiking neural networks, which she calls 'hairballs,' using the EONs framework to achieve high efficiency with very few neurons. She discusses the trade-offs between evolving network structure and tuning parameters via local learning rules like STDP, and the challenges of training these complex topologies compared to feed-forward models. The conversation with Dr. Giulia D’Angelo and Professor Ralph Etienne-Cummings of Johns Hopkins University explores the partitioning between evolutionary algorithms and learning mechanisms, emphasizing the need for meta-learning and hardware-in-the-loop co-design with memristive technologies.
