#NeuralOperators for real world seismology Full waveform inversion on a real seismic sites, San Gabriel, Chino, and San Bernardino basins in the Los Angeles metropolitan area. Steps: 1- Develop a domain-informed architecture 2- Train on generated function data resemble real phenomena 3- Do inversion on real data For the first time, we can remove the "linear approximation" limitation of prior art that for decades ignored importnat details in subsurface Earth. Now we understand our Earth with much strong lenses. For the first time we can run massive models with little memory footprint thanks to our domain specialized HelmholtzNO(HNO) architecture.

What a snow storm, I am glad my group's first happy hour (outdoor sitting at a pub) took place before this heavy and beautiful snow. #RLLab #NeuralOperatorLab
