Speed-accuracy trade-off for the diffusion models: Wisdom from nonequilibrium thermodynamics and optimal transport

no code implementations5 Jul 2024 Kotaro Ikeda, Tomoya Uda, Daisuke Okanohara, Sosuke Ito

We discuss a connection between a generative model, called the diffusion model, and nonequilibrium thermodynamics for the Fokker-Planck equation, called stochastic thermodynamics.

Generative Model for Constructing Reaction Path from Initial to Final States

no code implementations19 Jan 2024 Akihide Hayashi, So Takamoto, Ju Li, Daisuke Okanohara

Given their inherent complexity and nonlinearity, even generating a initial guess of these paths remains a challenging problem.
