arXiv:2601.18253v2 Announce Type: replace-cross Abstract: Accurate evaluation of user satisfaction is critical for iterative development of conversational AI. However, for open-ended assistants, traditional A/B testing lacks reliable metrics: explicit feedback is sparse, while implicit metrics are ambiguous. To bridge this gap, we introduce BoRP (Bootstrapped Regression Probing), a scalable framework for high-fidelity satisfaction evaluation. Unlike generative approaches, BoRP leverages the geometric properties of LLM latent space. It employs a polarization-index-based bootstrapping mechanism
The rapid development and deployment of open-ended conversational AI demand more robust evaluation methods than traditional A/B testing, which falls short in capturing nuanced user satisfaction. Current LLM evaluation techniques often struggle with scalability and alignment to human judgment, making this a critical area for progress.
Improved, scalable evaluation of LLMs is crucial for their iterative development and integration into critical applications, ensuring that sophisticated AI systems align with complex human expectations. This advancement allows for more effective refinement of AI models, directly impacting user adoption and trust.
The introduction of BoRP provides a more reliable and scalable framework for assessing user satisfaction in open-ended conversational AI, moving beyond sparse explicit feedback and ambiguous implicit metrics. This shift enables developers to better understand and improve the nuanced performance of large language models.
