The discussion revolves around the effects of partial observation in stochastic systems using the Koopman operator theory.
Data-driven algorithms based on the Koopman operator theory have shown progress in handling partial observations, aiming to connect with the Mori-Zwanzig formalism.
The importance of differentiating the state space and function space in stochastic systems is emphasized in the analysis.
Numerical experiments demonstrate the benefits of the delay embedding technique for partial observation in stochastic systems, revealing a power-law behavior in the accuracy of the additive noise amplitude.
