Such prediction depends on both long-term static attributes and short-term dynamic states derived from historical interaction logs. Recent Large Language Models (LLMs) offer strong long-context reasoning for constructing structured profiles from these logs, but existing solutions face two challenges for edge deployment: (1) profiling methods are typically domain-specific and lack a reusable abstraction across service scenarios, and (2) fine-tuning alignment models on heterogeneous edge clusters incurs high synchronization overhead due to the variance in input sequence lengths. To address these challenges, we propose CogGuard, a proactive-warning framework for edge intelligent services. CogGuard decouples offline LLM-based profile construction from online Small Language Model (SLM)-based score prediction through a shared static-dynamic profile-to-score pipeline, and instantiates it in two representative scenarios: educational performance warning and operational task outcome warning. For efficient profile construction, we design scenario-specific profiling methods with prefix-aligned KV-cache reuse to reduce repeated encoding overhead. For edge-side model alignment, we propose a length-aware distributed fine-tuning strategy with contrastive regularization to mitigate workload imbalance on heterogeneous clusters. Experiments on education and operation datasets show that CogGuard reduces profile construction time by up to 48% and distributed fine-tuning time by 19%, while achieving MAEs of 13.4 and 5.9, respectively, on 100-point-scale warning tasks. In the largest educational setting, CogGuard reduces prediction error by 15.4% compared with the strongest baseline.", "url": "https://wpnews.pro/news/cogguard-cognitive-and-operational-profiling-for-proactive-warning-in-edge", "canonical_source": "https://arxiv.org/abs/2606.15199", "published_at": "2026-06-16 04:00:00+00:00", "updated_at": "2026-06-16 04:21:25.819622+00:00", "lang": "en", "topics": ["large-language-models", "machine-learning", "ai-infrastructure", "ai-research"], "entities": ["CogGuard", "Large Language Models", "Small Language Model", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/cogguard-cognitive-and-operational-profiling-for-proactive-warning-in-edge", "markdown": "https://wpnews.pro/news/cogguard-cognitive-and-operational-profiling-for-proactive-warning-in-edge.md", "text": "https://wpnews.pro/news/cogguard-cognitive-and-operational-profiling-for-proactive-warning-in-edge.txt", "jsonld": "https://wpnews.pro/news/cogguard-cognitive-and-operational-profiling-for-proactive-warning-in-edge.jsonld"}}
