The framework uses structured domain representations and uncertain state-transition samples to extract, transform, and repair procedural rules, addressing the risk of omitted actions, incorrect step order, or logically flawed instructions. This approach aims to reduce the costly authoring burden for educational virtual laboratories by enabling more reliable use of LLM output as executable plans.", "body_md": "arXiv:2605.26333v1 Announce Type: new\nAbstract: Educational virtual laboratories can make experimental training more scala-ble, adaptive, and accessible, especially when students have limited access to physical laboratory facilities. However, authoring new simulated laboratory procedures remains costly: educators must describe new equipment, define how instruments and materials interact, and specify valid procedural flows that can be executed or assessed inside the virtual environment. Large lan-guage models can assist in this authoring process by generating detailed ex-perimental procedures, but their output should not be treated as directly exe-cutable plans. They may omit necessary actions, arrange steps in the wrong order, or produce instructions that are logically incorrect or incompatible with the laboratory equipment. This paper presents a prototype framework for managing uncertainty in LLM-generated procedural knowledge for virtu-al laboratory planning. The framework aims to reduce procedural uncertainty by using structured domain representations and uncertain LLM-generated state-transition samples to extract candidate procedural rules, transform them into explicit and inspectable constraints, and use them to repair uncertain procedural steps. Although the motivating domain refers to educational vir-tual laboratories, the underlying problem is more general: managing uncer-tain procedural knowledge for action planning in structured interactive envi-ronments. We illustrate the approach in a virtual laboratory domain involving laboratory instruments, containers, tools, and material-transfer actions.", "url": "https://wpnews.pro/news/managing-uncertainty-in-llm-generated-procedural-knowledge-for-virtual-planning", "canonical_source": "https://arxiv.org/abs/2605.26333", "published_at": "2026-05-27 04:00:00+00:00", "updated_at": "2026-05-27 04:31:56.945046+00:00", "lang": "en", "topics": ["large-language-models", "artificial-intelligence", "ai-research", "ai-agents"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/managing-uncertainty-in-llm-generated-procedural-knowledge-for-virtual-planning", "markdown": "https://wpnews.pro/news/managing-uncertainty-in-llm-generated-procedural-knowledge-for-virtual-planning.md", "text": "https://wpnews.pro/news/managing-uncertainty-in-llm-generated-procedural-knowledge-for-virtual-planning.txt", "jsonld": "https://wpnews.pro/news/managing-uncertainty-in-llm-generated-procedural-knowledge-for-virtual-planning.jsonld"}}
