Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The performance of a deep learning neural network improves logarithmically with increasing sample size.

    “It is generally accepted that the performance of a deep learning neural network improves logarithmically with increasing sample size [74-77].”
  • Good accuracies with reasonable classification results can be achieved with sample sizes as small as 150-500 images per class.

    “Good accuracies with reasonable classification results can be achieved with sample sizes as small as 150-500 images per class [76].”

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.
