klustereiksi

Klustereiksi is a Finnish translative plural form of the noun klusteri, meaning “into clusters.” The translative case expresses a change of state or role, so klustereiksi signals that something has been grouped into or transformed into clusters. In use, it often appears in contexts describing data segmentation or organizational grouping, as in “tiedot jaettiin klustereiksi,” meaning the data were divided into clusters.

In data analysis and statistics, klusterointi (cluster analysis) is the process of grouping similar observations into clusters. The plural translative klustereiksi is used when discussing the result of such a process, for example: “havainnot jaettiin klustereiksi käyttämällä k-means -algoritmia” (the observations were divided into clusters using the k-means algorithm). The term complements other Finnish forms such as klusteri (cluster), klusterit (clusters), or klusteriksi (into a cluster).

Usage notes: klustereiksi is a grammatical form rather than a distinct technical concept. It is typically used with verbs of division or transformation (jaettiin, muutettiin, ryhmiteltiin) to indicate that items are being organized into multiple clusters. The singular counterpart is klusteriksi, meaning “into a cluster.”

Etymology: klusteri is a loanword from English cluster, with the Finnish plural and case endings applied. The translative plural ending -eiksi yields klustereiksi, aligning with Finnish morphology for indicating transformation into multiple units.
