Table of Contents: Installation | Requirements | Quick Start | Citation
ARES is a groundbreaking framework for evaluating Retrieval-Augmented Generation (RAG) models. The automated process combines synthetic data generation with fine-tuned classifiers to efficiently assess context relevance, answer faithfulness, and answer relevance, minimizing the need for extensive human annotations. ARES employs synthetic query generation and Prediction-Powered Inference (PPI), providing accurate evaluations with statistical confidence.
What does ARES assess in RAG models?
ARES conducts a comprehensive evaluation of Retrieval-Augmented Generation (RAG) models, assessing the systems for context relevance, answer faithfulness, and answer relevance. This thorough assessment ensures a complete understanding of the performance of the RAG system.
How does ARES automate the evaluation process?
ARES minimizes the need for human labeling by leveraging fine-tuned classifiers and synthetic data. Its PPI component, Prediction-Powered inference, refines evaluations considering model response variability and provides statistical confidence in the results. By using fine-tuned classifiers and synthetically generated data, ARES cuts down on human labeling needs while providing accurate assessments.
Can ARES handle my custom RAG model?
Yes, ARES is a model-agnostic tool that enables you to generate synthetic queries and answers from your documents. With ARES, you can evaluate these generated queries and answers from your RAG model.
pip install ares-ai
Optional: Initalize OpenAI or TogetherAI API key with the following command:
export OPENAI_API_KEY=<your key here>
export TOGETHER_API_KEY=<your key here>
To implement ARES for scoring your RAG system and comparing to other RAG configurations, you need three components:
To get started with ARES, you'll need to set up your configuration. Below is an example of a configuration for ARES!
Copy-paste each step to see ARES in action!
Use the following command to quickly obtain the necessary files for getting started! This includes the 'few_shot_prompt' file for judge scoring and synthetic query generation, as well as both labeled and unlabeled datasets.
wget https://raw.githubusercontent.com/stanford-futuredata/ARES/main/datasets/example_files/nq_few_shot_prompt_for_judge_scoring.tsv
wget https://raw.githubusercontent.com/stanford-futuredata/ARES/main/datasets/example_files/nq_few_shot_prompt_for_synthetic_query_generation.tsv
wget https://raw.githubusercontent.com/stanford-futuredata/ARES/main/datasets/example_files/nq_labeled_output.tsv
wget https://raw.githubusercontent.com/stanford-futuredata/ARES/main/datasets/example_files/nq_unlabeled_output.tsv
OPTIONAL: You can run the following command to get the full NQ dataset! (347 MB)
from ares import ARES
ares = ARES()
ares.KILT_dataset("nq")
# Fetches NQ datasets with ratios including 0.5, 0.6, 0.7, etc.
# For purposes of our quick start guide, we rename nq_ratio_0.5 to nq_unlabeled_output and nq_labeled_output.
To get started with ARES's PPI, you'll need to set up your configuration. Below is an example of a configuration for ARES!
Just copy-paste as you go to see ARES in action!
