Bayesian Physic Informed Neural Network

Bayesian Physics-Informed Neural Networks (B-PINNs) combine the power of neural networks with Bayesian inference to solve and analyze partial differential equations (PDEs), offering a probabilistic framework for uncertainty quantification in their solutions and parameter estimations. Current research focuses on improving the efficiency and robustness of Bayesian inference methods, such as addressing the limitations of Hamiltonian Monte Carlo (HMC) through alternatives like stochastic gradient descent and Ensemble Kalman Inversion, and exploring various neural network architectures for improved performance on complex, multi-scale problems. This approach is significant for its ability to handle noisy data, provide reliable uncertainty estimates, and improve the accuracy and trustworthiness of physics-informed machine learning models across diverse scientific and engineering applications.
