APclust recommending a cluster for every pixel is probably a bug #19

Open PhDyellow opened 1 year ago

PhDyellow commented 1 year ago

Hubert's Gamma statistic applied here should be 0 for the case of either 1 cluster for everything, or every pixel in a separate cluster.

However, the search pattern used to find the best clustering parameter may not be returning non-zero Gamma statistics, leading to early exit with a terrible clustering solution.

Need to investigate and find solutions.

Low priority though, because it works more often than not.
