Title: UNIFICATION OF CLASSIFIER MODELS ACROSS DEVICE PLATFORMS
Abstract:
Techniques are provided for unification of classifier models across device platforms of varying form factors and/or sensor calibrations. A method includes extracting classification features from data provided by sensors associated with a first device platform (610). The method also includes applying a feature mapping function to the extracted features. The feature mapping function is configured to transform the features such that they are suitable for use by a classifier model that is trained on data provided by sensors associated with a second device platform (620). The method further includes executing the classifier model on the transformed features to generate classifications, for example recognized activities associated with use of the first device (630). The feature mapping function is based on application of a statistical distribution distance minimization between a sampling of data provided by sensors of the first device and sensors of the second device.
