In order to mitigate a need for reprogramming tire pressure sensors after tire rotation, tire change, etc., all sensors on a vehicle are preprogrammed with a lookup table that correlates modulation frequency to axle and wheel end positions on the vehicle. Dual antenna initiator coils are mounted to a vehicle such that each wheel end has one directional antenna directed toward it. Each initiator coil is programmed to modulate its transmission frequency by a predetermined modulation frequency such that each antenna transmits using a different modulation frequency. Each sensor receives a modulated signal, identifies the modulation frequency, and performs a table lookup to determine its axle and wheel end location. The sensor transmits its identified wheel end and axle location to a controller unit along with tire pressure status information for its wheel.

An information processing apparatus generates multiple combinations of sensor data inputted to a machine learning apparatus, inputs the combinations of sensor data to the machine learning apparatus, and generates a recognizer corresponding to each of the combinations of sensor data. Further, the performance of the recognizers is evaluated in accordance with expected performance required for the recognizers, and the combinations of sensor data corresponding to the recognizers satisfying the expected performance are outputted. Thus, the rates of contribution of two or more pieces of sensor data inputted to the machine learning apparatus are evaluated, and the configuration of sensors is optimized.
