What the Driller Wrote Instead

Text classification of 38,416 bore-log intervals, 2,811 of which describe nothing recovered

A research poster from the School of Underlying Conditions trains a linear text classifier on 38,416 free-text interval descriptions from 1,204 legacy water-bore logs and compares three treatments of the 2,811 entries that record no recovery: forcing a rock class, adding a tenth class, and rejecting below a confidence threshold. A probe trained on the loss wording alone names the rock bracketing a lost interval with accuracy 0.58 against a majority baseline of 0.29, and the authors propose reporting that suggestion apart from the rock classes.
