WebbThe Rand Index gives a value between 0 and 1, where 1 means the two clustering outcomes match identicaly. The Adjusted Rand Index rescales the index, taking into … Webbto more than one cluster. The package fclust is a toolbox for fuzzy clustering in the R programming language. It not only implements the widely used fuzzy k-means (FkM) algorithm, but also many FkM variants. Fuzzy cluster similarity measures, cluster validity indices and cluster visualization tools are also offered.

WebbRand Index and Adjust Rand Index. The Rand Index ( Rand, 1971) and the Adjusted Rand Index (Yeung, Ruzzo, 2001) are both commonly used indices to compare clustering results against external criteria ( Hubert, 1985 ).

WebbThe adjusted rand index of this solution should be close to 0. Thus: A high Rand index may be due to label distribution. A value of 0.95 can still be random! Adjusted rand values near 0 do indicate random results; values less than 0 even worse-than-guessing. Always prefer adjusted Rand to regular Rand index!
