Augmentierter

Augmentierter is the attributive or predicative form of the German past participle augmentiert, derived from the verb augmentieren. In German, augmentieren means to increase, enlarge, or supplement something. The word is mainly used in technical or scientific contexts to indicate that a thing has been augmented or enhanced relative to a baseline.

In mathematics and computer science, augmentierte is common in phrases like augmentierte Matrix (an augmented matrix), where a matrix [A|b] is formed by adjoining a column vector b to A. In data science and machine learning, derivate terms such as augmentierter Datensatz or augmentierte Datensätze refer to data augmentation, i.e., procedures that create additional training samples from existing data to expand the dataset and improve model performance.

In the broader discourse, augmentierte Realität appears as a direct calque of the English term augmented reality. While in everyday German the preferred translation is erweiterte Realität, augmentierte Realität is encountered in some technical writings and industry contexts, reflecting the influence of English terminology in tech sectors.

Grammatically, augmentierter is the masculine singular nominative form; the adjective adopts appropriate endings for gender, number, and case (z. B. eine augmentierte Realität, ein augmentierter Datensatz). The related verb form augmentieren is used to describe the action of augmenting, while the noun form augmentation denotes the process itself.
