Normaliseret gensidig information

Normaliseret gensidig information (NMI), populariseret af Danon et al. i 2005, er en ekstern evalueringsmetrik for klyngedannelse baseret på informationsteori. Den måler mængden af information, der deles mellem en forudsagt klyngedannelse og sande klasselabels, normaliseret til en skala mellem 0 og 1. En værdi på 1 indikerer perfekt overensstemmelse, mens 0 indikerer uafhængighed.
