When multiple related datasets are available, they provide additional information if the shared structure and variability are properly modeled. We propose a hierarchical Bayesian framework for probabilistic meta-learning in dynamical systems, modeling dataset-specific parameters as draws from a shared population distribution. A numerical ODE solver is embedded within gradient-based MCMC to enable efficient posterior inference of the shared population and dataset-specific parameter distribution. Experiments show improved predictive performance over unpooled methods, highlighting the potential for data-efficient system identification in settings with sparse data.", "url": "https://wpnews.pro/news/learning-dynamical-systems-from-multiple-sparse-datasets-a-hierarchical-bayesian", "canonical_source": "https://arxiv.org/abs/2606.24966", "published_at": "2026-06-25 04:00:00+00:00", "updated_at": "2026-06-25 04:26:36.603781+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/learning-dynamical-systems-from-multiple-sparse-datasets-a-hierarchical-bayesian", "markdown": "https://wpnews.pro/news/learning-dynamical-systems-from-multiple-sparse-datasets-a-hierarchical-bayesian.md", "text": "https://wpnews.pro/news/learning-dynamical-systems-from-multiple-sparse-datasets-a-hierarchical-bayesian.txt", "jsonld": "https://wpnews.pro/news/learning-dynamical-systems-from-multiple-sparse-datasets-a-hierarchical-bayesian.jsonld"}}
