The framework addresses representation-incoherent behaviors in existing steering vector methods by moving beyond binary positive-negative evaluation and discrete clustering metrics.", "body_md": "arXiv:2607.18259v1 Announce Type: new\nAbstract: Steering vectors (SVs), an inference-time intervention technique for large language models (LLMs), guide the generation process by adding a concept-specific direction vector to intermediate activations during inference. However, existing SV methods frequently yield representation-incoherent behaviors that undermine interpretability and fine-grained control, largely because prior work has focused on binary positive-negative steering evaluation while employing discrete clustering metrics that fail to capture the continuous spectrum of semantic alignment. In this work, we present the Probabilistic Concept-Aware Steering (PCS) framework for LLM inference. PCS preserves original task competence while providing controllable, safety-oriented semantic bias through concept-driven steering-vector retrieval and probabilistic strength calibration.", "url": "https://wpnews.pro/news/probabilistic-concept-aware-steering-for-trustworthy-llm-inference", "canonical_source": "https://arxiv.org/abs/2607.18259", "published_at": "2026-07-22 04:00:00+00:00", "updated_at": "2026-07-22 04:12:34.374240+00:00", "lang": "en", "topics": ["large-language-models", "ai-safety", "ai-research"], "entities": [], "alternates": {"html": "https://wpnews.pro/news/probabilistic-concept-aware-steering-for-trustworthy-llm-inference", "markdown": "https://wpnews.pro/news/probabilistic-concept-aware-steering-for-trustworthy-llm-inference.md", "text": "https://wpnews.pro/news/probabilistic-concept-aware-steering-for-trustworthy-llm-inference.txt", "jsonld": "https://wpnews.pro/news/probabilistic-concept-aware-steering-for-trustworthy-llm-inference.jsonld"}}
