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.

Bayesian System ID: Optimal management of parameter, model, and measurement uncertainty

no code implementations4 Mar 2020 Nicholas Galioto, Alex Gorodetsky

We evaluate the robustness of a probabilistic formulation of system identification (ID) to sparse, noisy, and indirect data.

Bayesian Identification of Nonseparable Hamiltonian Systems Using Stochastic Dynamic Models

no code implementations15 Sep 2022 Harsh Sharma, Nicholas Galioto, Alex A. Gorodetsky, Boris Kramer

This paper proposes a probabilistic Bayesian formulation for system identification (ID) and estimation of nonseparable Hamiltonian systems using stochastic dynamic models.

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.
