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 occupancy states at a time, the occupancy states including an occupied state and an unoccupied state, each of the sensors being in only one of a reporting state, in which the sensor reports the occupancy state of the respective cell, and a non-reporting state, in which the sensor does not report the occupancy state of the cell, 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 by the sensors to be in the occupied state, and a number of the sensors in the respective zone that are in the reporting state, at least one of the sensors of at least some of the zones being in the non-reporting state for at least one of the plurality of times; 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.
