Bayesian identification of nonseparable Hamiltonians with multiplicative noise using deep learning and reduced-order modeling

no code implementations23 Jan 2024 Nicholas Galioto, Harsh Sharma, Boris Kramer, Alex Arkady Gorodetsky

The results show that using the Bayesian posterior as a training objective can yield upwards of 724 times improvement in Hamiltonian mean squared error using training data with up to 10% multiplicative noise compared to a standard training objective.

Likelihood-based generalization of Markov parameter estimation and multiple shooting objectives in system identification

1 code implementation20 Dec 2022 Nicholas Galioto, Alex Arkady Gorodetsky

We then analyze this objective function in the context of several state-of-the-art approaches for both linear and nonlinear system ID.
