I have read through the scikit learn documentation and Googled to no avail. I have 2000 data sets, clustered as the picture shows. Some of the clusters, as shown, are wrong, here the red cluster. I need a metrics to method to validate all the 2000 cluster-sets. Almost every metric in scikit learn requires the ground truth class labels, which I do not think I have or CAN have for that matter. I have the hourly traffic flow for 30 days and I am clustering them using k-means. The lines are the cluster centers. What should I do? Am I even on the right track?
