Context A project where we classify human activity based on accelerometer, gyroscope and magnetometer data (device was attached to the feet) Content During the experimental data collection, we distinguished between the 2 activities (walking and running) based on 2 beats from the foot. That means, the user strikes twice on the ground, starts with walking, stops, strikes twice again, starts running, stops-two strikes-walks… and this continues. So the data is unlabeled. Acknowledgements Research project conducted at Cal State East Bay under Dr. Brad Bennett. Inspiration How would you go about labeling the data set?
