Comparison of Fuzzy Clustering Methods and Their Applications to Geophysics Data

Table 6

Number of resultant clusters using three algorithms and three performance measures with respect to maximum number of clusters and fuzzy or crisp cutoff. Resulting 4 tuples are for different data files: ⟨𝐴,𝐵,𝐶,𝐷⟩.
