Tested against years known from the sources

The model was cross-validated on scholars whose year of arrival is given in the sources: each year was predicted with that scholar left out of training and compared with the year in the source.

The table is recomputed from the validation predictions stored in the thesis file (rounded to whole years). The figures in the thesis report (§ 01) are averages over the folds, hence the small difference.

Every estimate is checked again

Missing birth years were filled with the median in the model, so some results are a by-product of that filling rather than a real estimate. These, and results falling after the scholar’s death, are not shown on the site.

  • 327 Usable Shown on the scholar page and in the atlas as “estimated”, with its margin of error.
  • 48 Artefact For students with no known birth year the filled-in year pushed the result to a fixed value; not shown.
  • 20 After death Falls after the scholar’s death; not shown.
