An autoencoder compression approach for accelerating large-scale inverse problems

no code implementations10 Apr 2023 Jonathan Wittmer, Jacob Badger, Hari Sundar, Tan Bui-Thanh

In this work, we propose a close-to-ideal scalable compression approach using autoencoders to eliminate the need for checkpointing and substantial memory storage, thereby reducing both the time-to-solution and memory requirements.

Solving Bayesian Inverse Problems via Variational Autoencoders

Further, this framework possesses an inherent adaptive optimization property that emerges through the learning of the posterior uncertainty.
