Abstract
There is described a floor selection system for location tracking within a structure. A communication component receives sensor data, associated with a beacon received from a tag, from sensors. A processor identifies features based on the sensor data, identifies decision tree stumps arranged in a particular order, assigns weights to the decision tree stumps based on the features and the feature thresholds. The processor further determines whether an aggregate of the weights is greater than a resultant threshold and selects a floor location of the tag based on whether the aggregate of weights is greater than the resultant threshold. The floor location is selected from floor locations of the structure proximal to the sensors.
