Isotonic Bellman calibration is a one-dimensional, model-agnostic post-processing method that reduces occupancy-balance violations while preserving ranking information in occupancy-ratio estimates

We introduce isotonic Bellman calibration, a one-dimensional, model-agnostic post-processing method that reduces these violations while preserving the ranking information in any initial occupancy-ratio estimate.
