Measuring all the noises of LLM Evals

📰 ArXiv cs.AI

Measuring noise in LLM evaluations is crucial for accurate results, and this research defines and measures three types of noise: prediction, data, and total noise.

advanced Published 31 Mar 2026
Action Steps
  1. Identify the sources of noise in LLM evaluations, including prediction noise and data noise
  2. Apply statistical methods to measure and separate signal from noise
  3. Calculate the total noise using the law of total variance
  4. Use the measured noise to improve the evaluation and validation of LLMs
Who Needs to Know This

Machine learning researchers and engineers on a team benefit from this research as it provides a framework for evaluating LLMs, while data scientists can apply the methods to improve the accuracy of their models.

Key Insight

💡 Separating signal from noise is crucial for effective LLM evaluations, and considering the unique noise characteristics of LLMs is essential.
