This research reveals exciting new ways Large Language Models (LLMs) encode and understand concepts! By differentiating between Function Vectors and Concept Vectors, this work opens doors to improved generalization and a deeper comprehension of how LLMs process information. The findings could lead to more robust and versatile Generative AI systems.
Key Takeaways
- •LLMs possess both Function Vectors (FVs) for in-context learning and Concept Vectors (CVs) for abstract concept representation.
- •CVs generalize better across different input formats and languages than FVs.
- •This research highlights a new understanding of how LLMs encode and utilize abstract concepts.
