더 깊은 질문

How does the sequential example selection approach of Se2 contribute to enhancing in-context learning compared to traditional methods

Se2's sequential example selection approach contributes to enhancing in-context learning by capturing the internal relationships and sequential information among examples. Traditional methods often overlook these aspects, leading to suboptimal performance in downstream tasks. By formulating the problem as a sequential selection issue, Se2 can model the conditional probability of example sequences given varying context inputs. This allows Se2 to better understand the interrelationships between examples and select more relevant and contextual prompts for in-context learning. Additionally, utilizing beam search helps construct diverse and high-quality example sequences, further enriching the contextuality and relevance of ICL prompts.

What are the potential limitations or biases that could affect the effectiveness of Se2 in real-world applications

Potential limitations or biases that could affect the effectiveness of Se2 in real-world applications include inherent biases present within large language models (LLMs) used for feedback. These biases may influence the selected examples and ultimately impact task performance. Additionally, computational resource constraints may limit the scalability of Se2 when dealing with larger datasets or more complex NLP tasks. Furthermore, relying solely on LLM feedback for example selection may introduce model-specific biases that could hinder generalizability across different models or tasks.
