A Text-Based Knowledge-Embedded Soft Sensing Modeling Approach for General Industrial Process Tasks Based on Large Language Model

no code implementations9 Jan 2025 Shuo Tong, Han Liu, Runyuan Guo, Xueqiong Tian, Wenqing Wang, Ding Liu, Youmin Zhang

To address these challenges, we propose a general framework named LLM-TKESS (large language model for text-based knowledge-embedded soft sensing), harnessing the powerful general problem-solving capabilities, cross-modal knowledge transfer abilities, and few-shot capabilities of LLM for enhanced soft sensing modeling.
