In real-world applications -- from biology to medicine and social science -- causal effects depend on regime (age, country, dose, genotype, or lab protocol). Our proposed judo calculus formalizes this context dependence formally as local truth: a causal claim is proven true on a cover of regimes, not everywhere at once. The Lawvere-Tierney modal operator j chooses which regimes are relevant; j-stability means the claim holds constructively and consistently across that family. We describe an algorithmic and implementation framework for judo calculus, combining it with standard score-based, constraint-based, and gradient-based causal discovery methods. We describe experimental results on a range of domains, from synthetic to real-world datasets from biology and economics. Our experimental results show the computational efficiency gained by the decentralized nature of sheaf-theoretic causal discovery, as well as improved performance over classical causal discovery methods.", "url": "https://wpnews.pro/news/decentralized-causal-discovery-using-judo-calculus", "canonical_source": "https://www.machinebrief.com/news/decentralized-causal-discovery-using-judo-calculus-tcqx", "published_at": "2026-07-28 04:00:00+00:00", "updated_at": "2026-07-28 05:56:46.396105+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence", "ai-research"], "entities": ["arXiv"], "alternates": {"html": "https://wpnews.pro/news/decentralized-causal-discovery-using-judo-calculus", "markdown": "https://wpnews.pro/news/decentralized-causal-discovery-using-judo-calculus.md", "text": "https://wpnews.pro/news/decentralized-causal-discovery-using-judo-calculus.txt", "jsonld": "https://wpnews.pro/news/decentralized-causal-discovery-using-judo-calculus.jsonld"}}
