Hi,
I have gotten a lot of error messages when trying to use any of the clustering algorithms on time series data. I structured my data file like in contexSAX.txt test file, and still get the various error messages on all clustering algorithms.
I am trying to find if groups of learners progressed through the task in similar way; ie. can we cluster students processes into certain types of progress.
Below is an example of the data, I have 9 groups in total.
@NAME=GROUP1
300,300,300,300,200,200,300,300,300,300,200,200,200,200,150,100,100,100,100,100,150,100,300,300,300,300,100,100,150,100,300,300,300,300,350,300,200,200,200,200,300,300,300,300,300,300,300,300,300,300,300,300,100,100,100,100,100,100,200,200,350,300,350,300,350,300,300,300,150,100,350,300,300,300,300,300,300,300,300,300,300,300,300,300,300,300,300,300,350,300,300,300,300,300,300,300,300,300,300,300,275,300,300,300,200,200,400,400,300,300,200,200
@NAME=GROUP2
200,200,200,200,300,300,100,100,100,100,100,100,300,300,100,100,100,100,300,300,100,100,300,300,100,100,300,300,300,300,300,300,300,300,300,300,300,300,350,300,150,100,300,300,350,300,300,300,300,300,300,300,300,300,300,300,300,300,350,300,300,300,300,300,300,300,100,100,150,100,300,300,300,300,350,300,350,300,350,300,350,300,300,300,300,300,300,300,150,100,300,300,150,100,350,300,300,300,300,300,200,200
Any help would be appreciated!
Kind regards,
