arXiv:2602.15778v2 Announce Type: replace Abstract: Evaluating the quality of automatically generated text often relies on LLM-as-a-judge (LLM-judge) methods. While effective, these approaches are computationally expensive and require post-processing. To address these limitations, we build upon ParaPLUIE, a perplexity-based LLM-judge metric that estimates confidence over ``Yes/No'' answers without generating text. We introduce *-PLUIE, task specific prompting variants of ParaPLUIE and evaluate their alignment with human judgement. Our experiments show that personalised *-PLUIE achieves stronge
The proliferation of LLMs necessitates more efficient and reliable evaluation methods, especially as these models become central to various applications. This research addresses the current computational and practical limitations of existing LLM-as-a-judge approaches.
Improved and more efficient evaluation metrics for LLMs directly impact the speed of AI development, the quality of AI products, and the cost of deploying AI systems, making advanced applications more broadly accessible.
The ability to evaluate AI-generated text more quickly, accurately, and cost-effectively, reducing reliance on computationally intensive methods and enabling more granular feedback loops in AI development.
