A Bayesian Framework for learning governing Partial Differential Equation from Data

no code implementations8 Jun 2023 Kalpesh More, Tapas Tripura, Rajdip Nayek, Souvik Chakraborty

To accelerate the overall process, a variational Bayes-based approach for discovering partial differential equations is proposed.

MAntRA: A framework for model agnostic reliability analysis

no code implementations13 Dec 2022 Yogesh Chandrakant Mathpati, Kalpesh Sanjay More, Tapas Tripura, Rajdip Nayek, Souvik Chakraborty

A two-stage approach is adopted: in the first stage, an efficient variational Bayesian equation discovery algorithm is developed to determine the governing physics of an underlying stochastic differential equation (SDE) from measured output data.
