We Need to Talk about Standard Splits

Abstract

It is standard practice in speech & language technology to rank systems according to performance on a test set held out for evaluation.However, few researchers apply statistical tests to determine whether differences in performance are likely to arise by chance, and few examine the stability of system ranking across multiple training-testing splits.We conduct replication and reproduction experiments with nine part-of-speech taggers published between 2000 and 2018, each of which reports state-of-the-art performance on a widely-used "standard split".We fail to reliably reproduce some rankings using randomly generated splits.We suggest that randomly generated splits should be used in system comparison.

  • Especially when sample sizes are small, significance testing and uncertainty quantification are important steps toward reproducibility.

    From Leakage and the reproducibility crisis in machine-learning-based science (2023) · cites this paper as [85]

    The Introduction (‘Hypothesis testing for system comparison’; page unavailable) argues that performance scores are estimates rather than exact quantities and that hypothesis testing helps avoid false claims of improvement. The Methods (‘Metrics’; page unavailable) reports confidence intervals and a significance test. The paper does not specifically say these steps are especially important when sample sizes are small.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
