Never Asked Is Not Lost

Characteristic-relation rough sets over soil profiles described on three editions of the field card

A research poster from the School of Underlying Conditions applies characteristic-relation rough sets to 1,846 reference soil profiles described on three editions of a field card, reading the fields the older cards never asked as do-not-care conditions and illegible entries as lost values. The edition-aware encoding lowers the quality of classification from 0.78 to 0.52, and re-describing 64 of the 388 surviving first-edition monoliths, chosen greedily by conflict, restores it to 0.70.
