Embedding by Elicitation: Dynamic Representations for Bayesian Optimization of System Prompts
The paper discusses a new framework called ReElicit for optimizing system prompts in AI using Bayesian methods. It addresses the challenge of tuning prompts based on aggregate feedback rather than detailed critiques. The results indicate that this approach can enhance the performance of AI systems by adapting to feedback over time.
- ▪ReElicit is a Bayesian optimization framework designed for system prompts in AI.
- ▪The framework operates under conditions where feedback is limited to aggregate metrics.
- ▪ReElicit has shown strong performance across multiple optimization tasks, outperforming existing methods.

Yet they are difficult to tune when feedback is available only as aggregate metrics rather than per-example labels, failures, or critiques.
