Function Documentation

integer trajectory_transformation_random_shift	(	text	dataset,
		float	rate,
		float	distance,
		boolean	save = `true`,
		text	new_dataset_name = `"transformed"`,
		boolean	csv_file = `true`
	)

This function performs trajectory transformation by shifting randomly rate % points.

Parameters

[in]	dataset	Name of the dataset
[in]	rate	Percentage of points to be shifted, 0 ≤ rate ≤ 1
[in]	distance	Float which indicates the maximum distance of the shifted point from the initial one
[in]	save	Boolean which indicates whether the new dataset will be saved in Hermes
[in]	new_dataset_name	The name with which the transformed dataset will be stored in Hermes
[in]	csv_file	Boolean which indicates whether the new dataset will exported in a cvs format (traj_new.txt)
