Prometheus-Eval & Prometheus 2: Advancing NLP Evaluation
Overview
In natural language processing (NLP), the need to enhance language models’ capabilities for text generation, translation, and sentiment analysis is crucial. Prometheus-Eval and Prometheus 2 provide advanced evaluation tools for language models, addressing this need effectively.
Prometheus-Eval
Prometheus-Eval is a repository that offers tools and methods for training, evaluating, and using language models. It includes the Prometheus-eval Python package, which supports absolute and relative grading methods, along with evaluation datasets and scripts for custom model training.
Prometheus 2
Prometheus 2 is a state-of-the-art evaluator language model that offers significant improvements over its predecessor. It supports direct assessment and pairwise ranking formats, showing high accuracy and consistency in evaluating language models.
Key Features
- Simulates human judgments
- Supports proprietary LM-based evaluations
- Accessible with consumer-grade GPUs
- Efficient and transparent evaluation framework
Prometheus 2 Performance
- Prometheus 2 (8x7B) shows Pearson correlation of 0.6 to 0.7 with GPT-4-1106
- Prometheus 2 (8x7B) scores 72% to 85% agreement with human judgments
- Prometheus 2 (7B) achieves at least 80% of the larger model’s evaluation statistics
