A technical analysis explains the statistical necessity of paired bootstrapping in evaluating AI model performance, particularly when comparing a baseline system against a trained LoRA model. The author demonstrates that using the same set of tasks for both evaluations, rather than independent sets, is crucial for accurate uncertainty estimation. While pairing reduces the standard error by incorporating covariance, the actual benefit in this specific case was modest due to a low correlation between the models' performance on individual tasks.
