Proxy Model
Proxy models are surrogate models that approximate the behavior of complex systems, reducing computational costs and improving efficiency in various applications. Current research focuses on developing physics-aware and data-driven proxy models for diverse domains, including process systems, natural language processing, and reinforcement learning, often employing techniques like neural networks, Markov Decision Processes, and information-theoretic approaches. These advancements are significant because they enable faster model selection, more efficient training of large language models, improved explainability of complex systems, and enhanced privacy in federated learning settings. The resulting improvements in speed, efficiency, and explainability have broad implications across numerous scientific fields and practical applications.
