cmeans {e1071} vs. fanny {cluster}

I was trying to do fuzzy k-means clustering with a dataset of dimension 15'000 x 7. I first tried the function fanny and it took R almost 7 hours to get a result (I also tried other parameters but it's always slow; with a sample of 5'000 rows it…

Save image that has been segmented in matlab

I would like to know how can we save an image that has been segmented (using fuzzy c-means method) in MATLAB where the end product are images of each cluster group. I would like to save the images to use later.

Why is Fuzzy CMeans compute time varying widely for m?

I am running a cmeans analysis on a series of 20k document embeddings, with the number of clusters set to 400. For m (fuzziness parameter) from 2-4, the algorithm completes in hours, however for m <1.5 it is taking days? I am struggling to…
