The paper introduces methods for evaluating machine learning models’ performance by determining whether an evaluation dataset has enough responses per item to reliably compare model performances. It highlights the limitations of traditional accuracy, precision, and recall metrics due to AI models’ stochasticity and human raters’ disagreements. The authors apply their methods to existing gold standard test sets with multiple responses per item, showing that most datasets are insufficient for reliable performance comparisons. They also propose a method to estimate the required number of responses per item in hypothetical datasets with similar response distributions.

The paper looks at how we evaluate machine learning models. Right now, we use simple metrics like accuracy and precision to compare models. But AI models can behave differently each time they’re used, and human raters don’t always agree on what’s correct. The authors suggest new methods to figure out if an evaluation dataset has enough responses to accurately compare model performances. They tested these methods on existing datasets and found that most of them have too few responses. They also proposed a way to estimate how many responses are needed for hypothetical datasets.
