Reimagining Language Model Evaluation: The Power of PoLL
Artificial intelligence research has taken a revolutionary leap forward with the introduction of a new evaluation strategy, known as a Panel of Large Language Models Evaluators (PoLL). Traditional single-model evaluations, popularized by models like GPT-4, have been subject to criticisms. The high costs, potential bias, and overarching reliance on a single large model are among the notable drawbacks.
The AI research team from Cohere propose a radically different solution – PoLL. This involves multiple smaller language models working in unison to objectively evaluate the outputs. The promise of PoLL lies in bias reduction and dramatically reduced evaluation costs – seven times more cost-effective than a single large model, according to the researchers.
This strategy also led to higher performance levels as demonstrated by six different datasets used in various settings: single-hop question answering, multi-hop QA, and Chatbot Arena. The study shows PoLL's closer alignment with human evaluations rather than depending on one large model.
Interestingly, the areas where GPT-4 significantly deviated from human assessments have been flagged. In these situations, PoLL's diverse panel effectively curbs intra-model scoring biases. This could potentially unleash new levels of precision and cost efficiency in large language model assessments.
