The Cell Below Five

Reconstructing a grain co-operative's suppressed delivery counts from its own year-to-date tables

A research poster from the School of Continuous Improvement runs one integer program over three seasons of a regional grain co-operative's published monthly and year-to-date receival tables and recovers exactly 941 of the 1,117 monthly cells it suppressed for falling under five loads, against 253 from the monthly tables alone. It then prices the same releases under zero-concentrated differential privacy at a median error of three loads a cell.
