ADAPTIVE SENSOR SAMPLING FOR POWER EFFICIENT CONTEXT AWARE INFERENCES
First Claim
1. A method for performing context inference for a mobile device comprising:
- receiving data from at least a first sensor;
performing a first classification of the data from the at least first sensor;
determining a confidence value for the first classification;
activating a second sensor based on a determination the confidence value of the first classification fails to meet a confidence threshold; and
performing a second classification of a second data sample from the activated second sensor jointly with the data from the at least first sensor.

Abstract
Disclosed is a system, apparatus, computer readable storage medium, and method to perform a context inference for a mobile device. In one embodiment, a data processing system includes a processor and a storage device configurable to store instructions to perform a context inference for the data processing system. Data may be received from at least a first sensor, and a first classification of the data from the sensor may be performed. Confidence for the first classification can be determined and a second sensor can be activated based on a determination that the confidence fails to meet a confidence threshold. A data sample classification from the activated second sensor may be classified jointly with the data from first sensor
