Optimizing Scoring Models: Effective Prompting Formats

tldt arrow

Too Long; Didn't Read

This section illustrates the use of prompting formats for scorer large language models (LLMs), focusing on examples of Q_begin, Q_end, and A_begin formats when the "QA" pattern is present. It emphasizes that the "QA" pattern is eliminated in instruction-tuned scorer models like text-bison when employing the Q_begin and Q_end formats.

Figure 14, 15, and 16 show examples of the Q_begin, Q_end, and A_begin prompting formats when the “QA” pattern is present. The “QA” pattern is eliminated when prompting instruction-tuned scorer models like text-bison with the Q_begin and Q_end formats (Figure 17 and 18).
