AppleSelfReflect: Can LLMs Communicate Their Internal Answer Distribution?
Read Full ArticleSummary
The article discusses the SelfReflect metric, which aims to enhance the transparency of large language models (LLMs) by allowing them to communicate their internal answer distributions. Traditional methods of indicating uncertainty, such as hedging words or numerical scores, are deemed insufficient. The authors propose that LLMs should reflect on their internal belief distributions and provide a summary of possible answers along with their likelihoods. Through empirical studies, the authors demonstrate that while current LLMs struggle to express their uncertainties effectively, they can generate faithful summaries when provided with multiple outputs. This finding highlights the potential for improved communication of uncertainty in LLMs and sets the stage for future developments in this area.
Key Learnings
- 1The SelfReflect metric provides a quantitative measure of the faithfulness between an LLM's summary and its internal answer distribution.
- 2Current LLMs are generally incapable of revealing their uncertainties effectively without additional support, such as sampling multiple outputs.
- 3The approach of feeding back multiple outputs into the context can significantly enhance an LLM's ability to communicate its uncertainties.
- 4Understanding and quantifying uncertainty in LLMs is crucial for their deployment in real-world applications.
