Piirteistökokoelmaksi

Piirteistökokoelmaksi is a Finnish linguistic construction used to indicate that something should be treated or used as a collection of features. It is formed from the word for features (piirteet) and the word for collection (kokoelma) with the suffix -ksi, which expresses designation or conversion in Finnish. The form is encountered primarily in technical writing, data science, and machine learning contexts to label a representation or stage as a feature collection.

The standard way to refer to this concept in Finnish is often piirteistökokoelmaksi, reflecting typical phonological and morphological patterns in Finnish. The form piirteistökokoelmaksi is also found in practice, particularly in informal, transitional, or dialect-influenced text. In any case, the intent is clear: to describe a representation that aggregates individual features into a structured set that can be used for analysis or modeling.

Usage of piirteistökokoelmaksi appears in documentation and methodological descriptions where data are transformed or interpreted. It signals that raw observations or extracted attributes should be considered as a cohesive collection of features, rather than as isolated measurements. This distinction is common in data pipelines, feature engineering, and model input specification, where the emphasis is on the role of a data object as a feature collection.
