Claim One:
1. A computer implemented method comprising: receiving occupancy data for each of a plurality of zones, each zone comprising a respective set of cells and including a sensor for each of the cells in the set of cells, each of the cells being in one of a plurality of states at a time, the states including an occupied state and an unoccupied state, each of the sensors being in one of a reporting state and a non-reporting state at a time, the occupancy data comprising, for each of a plurality of times: an observed occupancy, which is based on a number of cells in the respective zone that are reported to be in the occupied state, and a number of the sensors in the respective zone that are in the reporting state; with a processor, learning at least one predictive occupancy model configured for predicting an occupancy of at least one of the zones, the learning being based on at least a portion of the received occupancy data, at least one of the at least one predictive occupancy models including a sensor noise model which assumes that a probability of a sensor being in the reporting state is dependent on whether the respective cell is in the occupied state.
