In experiments on linear, chaotic, and wireless tracking environments, CA-NKCF outperformed traditional Kalman and particle filters and purely model-free neural networks, maintaining robustness across varying noise levels, topologies, and state dimensions.", "body_md": "arXiv:2606.28441v1 Announce Type: new\nAbstract: Online latent state estimation constitutes a fundamental challenge within the artificial intelligence field, serving as a foundational tool for diverse applications, including sequential decision making, anomaly and change-point detection. In this paper, a novel online distributed sensing framework, where agents collaborate and exchange information to perform latent state estimation, is presented. The proposed estimator combines available partial domain knowledge with the representation capabilities of deep neural networks. In particular, the designed sensing framework incorporates prior estimates, optimized consensus weights, and Kalman-like recursive updates to perform decentralized inference, without relying on knowledge of noise statistics. Extensive experiments on linear, chaotic (Lorenz), and practical wireless tracking environments reveal that the proposed Covariance-Agnostic Neural Kalman Consensus Filter (CA-NKCF) outperforms traditional distributed Kalman and particle filters as well as purely model-free deep neural networks, exhibiting robustness even when the underlying motion and observation models are misspecified. It is also demonstrated that CA-NKCF's performance advantage remains stable across varying noise levels, random communication topologies, latent state dimensions, and observation clutter densities induced by scattering objects in wireless systems.", "url": "https://wpnews.pro/news/learning-to-distributedly-estimate-under-partially-known-dynamics-a-covariance", "canonical_source": "https://arxiv.org/abs/2606.28441", "published_at": "2026-06-30 04:00:00+00:00", "updated_at": "2026-06-30 04:29:24.914859+00:00", "lang": "en", "topics": ["machine-learning", "neural-networks", "artificial-intelligence"], "entities": ["CA-NKCF", "Lorenz"], "alternates": {"html": "https://wpnews.pro/news/learning-to-distributedly-estimate-under-partially-known-dynamics-a-covariance", "markdown": "https://wpnews.pro/news/learning-to-distributedly-estimate-under-partially-known-dynamics-a-covariance.md", "text": "https://wpnews.pro/news/learning-to-distributedly-estimate-under-partially-known-dynamics-a-covariance.txt", "jsonld": "https://wpnews.pro/news/learning-to-distributedly-estimate-under-partially-known-dynamics-a-covariance.jsonld"}}
