Webb13 apr. 2024 · In this paper, we propose a fully data driven algorithm to learn the prior and posterior pdfs conditioned on given observations. Our learning is based on a set of trajectories of the model and observations. It aims to correct the pdfs by optimizing likelihood-based loss functions in the sense of the Kullback-Leibler (KL) divergence. WebbPhysics-informed machine-learning (PIML) enables the integration of domain knowledge with machine learning (ML) algorithms, which results in higher data efficiency and more stable predictions. potentially violent persons register scotland
