Editing Confusion matrix (section)

== Confusion matrices with more than two categories ==

Confusion matrix is not limited to binary classification and can be used in multi-class classifiers as well. The confusion matrices discussed above have only two conditions: positive and negative. For example, the table below summarizes communication of [[Whistled_language#Techniques|a whistled language]] between two speakers, with zero values omitted for clarity.<ref>{{cite journal |last1=Rialland |first1=Annie |title=Phonological and phonetic aspects of whistled languages |journal=Phonology |date=August 2005 |volume=22 |issue=2 |pages=237–271 |doi=10.1017/S0952675705000552 |citeseerx=10.1.1.484.4384 |s2cid=18615779 }}</ref>
