I have a data sets which has two columns. I am trying to apply k mean clustering but result does not satisfy me. What i see with my naked eye is better than the clustering result so is there anyway to improve my clustering. Here is the data without clustering. I can basically see three clusters
When i apply k mean clustering with the following code i get the below result which does not make a sense. I think red and green should be in the same cluster and the blue should be separated from ~200 (on the x-axis).
opts = statset('Display','final');
[idx,C] = kmeans(wpf,3,'Distance','sqeuclidean',...
legend('Cluster 1','Cluster 2','Cluster 3',...
I need you guys help. If you are interested, i can also provide raw data sets.
