LAST-RAG: Literature-Anchored Stochastic Trajectory Retrieval-Augmented Generation for Knowledge-Conditioned Degradation Model Selection
The paper introduces LAST-RAG, a method for selecting degradation models based on observed health indicator trajectories and domain-specific knowledge. It addresses limitations of existing model selection methods that rely solely on statistical fit. The proposed approach integrates theoretical evidence and uncertainty reasoning to enhance model selection accuracy.
- ▪LAST-RAG stands for Literature-Anchored Stochastic Trajectory Retrieval-Augmented Generation.
- ▪The method improves upon traditional statistical model selection by incorporating domain knowledge.
- ▪Simulation experiments show that LAST-RAG outperforms existing statistical and prognostic methods.
