Overview / Usage

Wearable and Mobile Device Accelerometer has linear calibration measurements. This provides us with two metrics sensitivity and offsets in each of the axes (X, Y, Z) to model. Hence there are 6 metrics for each device. Adaptive Neural Networks is used to learn these parameters to uniquely identify a device.

In the figure, You can see the POC. Three clusters represent (the Z axes) sensitivity and offsets of three devices.
Example Devices used: Moto G, Mi4i, and Ipad.
