DEVICE AND METHOD FOR DETECTING USER ACTIVITY BY PARALLELIZED CLASSIFICATION

摘要

A device, particularly a mobile device is provided, comprising a plurality of sensors. The mobile device is configured to, in a testing phase, obtain data from the plurality of sensors; apply a plurality of trained classifiers on the obtained data, wherein each trained classifier is associated to one of the sensors; estimate, in each of the plurality of trained classifiers, a probability for each of a plurality of classes of a transportation mode of the device; and determine a transportation mode of the device based on the probabilities estimated in each of the trained classifiers. This disclosure also presents a device, particularly a server device. The server device is configured to, in a training phase, obtain training data of another device, particularly mobile device, comprising a plurality of sensors; associate a classifier to each of the sensors; train each classifier using the obtained training data; and provide the trained classifiers to the another device.
