AutoEval Done Right: Using Synthetic Data for Model Evaluation

Understand

The evaluation of machine learning models using human-labeled validation data can be expensive and time-consuming.

• AI-labeled synthetic data can be used to decrease the number of human annotations required for this purpose in a process called autoevaluation.
• We suggest efficient and statistically principled algorithms for this purpose that improve sample efficiency while remaining unbiased.
• These algorithms increase the effective human-labeled sample size by up to 50% on experiments with GPT-4.
