This repository contains my solutions for a lecture about fuzzy clustering. No guarantee for correctness or anything, but maybe someone finds the code useful anyway.
Content:
- Fuzzy C-Means (FCM)
- A benchmark of various different methods to calculate covariance matrices
- Various cluster validity indices
- Partition Coefficient (PC)
- Normalized Partition Coefficient (NPC)
- Fuzzy Hypervolume (FHV)
- Fukuyama-Sugeno Index (FS)
- Xie-Beni Index (XB)
- Beringer-Hullermeier Index (BH)
- Bouguessa-Wang-Sun index (BWS)
Here is a plot of some data clustered with FCM:
And here is a plot of the various cluster validity indices for that data clustered with different number of clusters:
