Diffusion models as probabilistic neural operators for recovering unobserved states of dynamical systems

no code implementations11 May 2024 Katsiaryna Haitsiukevich, Onur Poyraz, Pekka Marttinen, Alexander Ilin

In this work, we show that diffusion-based generative models exhibit many properties favourable for neural operators, and they can effectively generate the solution of a PDE conditionally on the parameter or recover the unobserved parts of the system.

Mixture of Coupled HMMs for Robust Modeling of Multivariate Healthcare Time Series

1 code implementation14 Nov 2023 Onur Poyraz, Pekka Marttinen

Experiments on challenging real-world epidemiological and semi-synthetic data demonstrate the advantages of the M-CHMM: improved data fit, capacity to efficiently handle missing and noisy measurements, improved prediction accuracy, and ability to identify interpretable subsets in the data.
