Average classification accuracy over the three datasets. For each dataset, we show the average classification accuracy (y-axis) as we increase the number of sampled spatio-temporal points (x-axis). Note that as little as 1 spatio-temporal point is sufficient to correctly classify more than 90% of the users, in 2 out of 3 datasets. Here the red line refers to the case where the correct trajectory is the nearest one, whereas the red line refers to the case where the correct trajectory is either the first or the second nearest one.
