ARI stands for adjusted Rand index and AMI stands for adjusted mutual information.

They are metrics for clustering.


  • ARI might take negative values.

  • The AMI takes a value of 1 when the two partitions are identical and 0 when the MI between two partitions equals the value expected due to chance alone.
