Public Transport Driver Identification System Using Histogram of Acceleration Data

Algorithm 3

Threshold calculation for each driver using the KNN.

Input:k constant in KNN k

validation data validateData

training data trainData

Output:threshold for each driver threshold_d

1:for each driver d  do:

2:validateData_d = validateData that keep only driver d

3:for each  validateData_d  do:

4:kList_d = find k nearest neighbor in trainData

5:topkList_d = keep maximum distance from kList_d

6:end for

7:threshold_d = average distance in topkList_d

8:end for
