Full Summary
Physics-informed AI aims to bridge the gap between machine learning and physics, addressing the need for models that can understand and apply physical laws. In this part of the series, supervised fine-tuning of a large language model (LLM) is explored as a method to enhance its engineering dialogue capabilities.
The approach involves training the LLM on a dataset that includes engineering concepts while ensuring that a separate 'checker' component retains ownership of the physics knowledge. This method allows the LLM to generate relevant engineering insights while adhering to physical constraints.
Results indicate that this fine-tuning significantly improves the model's contextual understanding and response accuracy in engineering scenarios. The implications for engineers and researchers include the potential for more effective AI tools that can assist in engineering design and analysis, ultimately leading to better decision-making.
