Yhdenmodinen

Yhdenmodinen is a Finnish term used in technical and scientific writings to describe something that involves or relies on a single modality or data type, as opposed to multiple modalities. It is often encountered in discussions of signals, imaging, data analysis, and communication where the focus is on one channel or form of information rather than on combining several.

Etymologically, the word is a compound built from the idea of “one” (yksi, expressed here as the genitive form yhden) and a suffix related to modality or mode (modinen), forming an adjective that translates roughly to “single-modality” in English. The term appears mainly as a neologism or calque in Finnish technical literature and is used to convey unimodal or single-source characteristics. Its exact nuance can vary by field, since different disciplines distinguish between unimodal (one modality) and multimodal (multiple modalities) data, signals, or analyses.

In practice, yhdenmodinen is used to describe data, methods, or systems that operate with one data stream or sensory channel. Examples include a yhdenmodinen signaali (a signal from a single modality), yhdenmodinen kuvaus (single-modality imaging), or yhdenmodinen analyysi (analysis based on one data type). It is commonly contrasted with multimodaalinen or monimodaalinen terminology, which refer to multiple modalities or data types.

The term is not yet standardized across all Finnish technical communities, and some authors prefer alternative translations such as unimodaali or yksinkertainen modi- tahller. Nevertheless, yhdenmodinen serves as a concise descriptor in contexts emphasizing a single-source approach.
