selektiv

Selektiv is a term used in several domains to describe systems or processes that intentionally select or filter components based on predefined criteria. It is often used as a brand name for products or technologies that implement selective behavior. The word appears in English-language technical writing and in branding across Europe, sometimes without a fixed definition beyond its general sense of selectivity.

In computing and data science, Selektiv refers to families of feature-selection and sample-selection methods. These approaches aim to reduce dimensionality, improve computational efficiency, or enhance model performance by retaining only features or instances deemed most informative according to a scoring function, statistical criterion, or heuristic.

In materials science and chemical engineering, Selektiv describes selective separation technologies. Examples include membranes, sorbents, and catalytic supports designed to preferentially interact with specific molecules, enabling gas separations, water purification, or selective catalytic processes.

In medicine and biology, selective imaging and targeting use principles of selectivity to highlight or treat particular tissues, cells, or biomarkers while minimizing effect on others.

Legacy and variants: The name is used by multiple vendors for filtration cartridges, analytical tools, or software modules that implement selective behavior. Because the term is broad and non-specific, its exact meaning depends on context and industry.
