Researchers at The University of Texas at Austin developed a two-stage context distillation method to parametrically update large language models, allowing them to propagate new knowledge for broader inferences. This approach achieved significantly higher inference accuracy (e.g., +31.8% on ENTITY INFERENCES) than previous knowledge editing techniques while preserving model specificity and scaling to hundreds of simultaneous updates.
Key insights
- Context distillation successfully teaches LLMs to make inferences from newly acquired knowledge, bridging the performance gap between retrieval-augmented methods and prior parametric editing techniques.
- The definitional content of the new knowledge is paramount for successful injection and propagation, highlighting its central role in shaping the model's updated understanding.
- The method maintains high specificity, allowing for targeted knowledge updates with minimal degradation of the model's performance on unrelated tasks or existing knowledge.
