Description:
 def _getRadius(self, location):
 """ Returns the radius associated with the given location. This is a bit of an awkward argument to the CoordinateEncoder, which specifies the resolution (in was used to encode differently depending on speed in the GPS encoder). Since the coordinates are object-centric, for now we use the "point radius" as an heuristic, but this should be experimented and improved. """

    # TODO: find better heuristic
    return int(math.sqrt(sum([coord ** 2 for coord in location])))
