cluster with users, but no action pattern(s)

[wunderwuzzi1975]

Hi @xychang,

thank your very much for the paper you wrote & the great software you provided. I had no problems to get the code running under Windows 7 and Python 3.6.9. When I looked at the results that I got for the clickstream data that I put in from my webservice, I recognized a cluster (cluster-ID 43, see screenshot provided) that contains 2 users, but no action pattern(s). I double checked my input data, but I was not able to determine any (obvious) anomalies. Can you enlight me on this issue? I have attached the data (clickstreams_Heilmittel_Verloren.txt) to this issue.

Kind regards Michael
