Attaining entropy production and dissipation maps from Brownian movies via neural networks

1 code implementation29 Jun 2021 Youngkyoung Bae, Dong-Kyum Kim, Hawoong Jeong

We show that our method accurately measures the EP and creates a dissipation map in two nonequilibrium systems, the bead-spring model and a network of elastic filaments.

Learning entropy production via neural networks

2 code implementations9 Mar 2020 Dong-Kyum Kim, Youngkyoung Bae, Sangyun Lee, Hawoong Jeong

This Letter presents a neural estimator for entropy production, or NEEP, that estimates entropy production (EP) from trajectories of relevant variables without detailed information on the system dynamics.
