    • n gnat A small two-winged fly, Culex pipiens, of the family Culicidæ, suborder Nemocera, and order Diptera, called in America mosquito. The male has plumose antennæ and does not bite, though having a kind of rostrum or beak. The female bites with a stinging proboscis, and her antennæ are filiform and but slightly pilose. The larvæ and pupæ are aquatic. According to Westwood the term gnat should be restricted to insects of the family Culicidæ, and midge should be applied to the Chironomidæ.
    • n gnat Any other insect of the family Culicidæ.—
    • n gnat A nemocerous dipterous insect; a midge. There are several families. The Mycetophilidæ are known as fungus-gnats or agaric-gnats. The Cecidomyiidæ include the gall-gnats. The buffalo-gnat is a species of Simidium, family Simuliidæ (see cut under Simulium); other simuliids are known as black-gnats and turkey-gnats. Species of Bibionidæ and Chironomidæ are also called gnats. See the compounds and technical words.
    • n gnat A bird: same as knot.

His circuit round the Shed, the Tree;

A summer-night's serenity.

Proceeded over all his features.

In science:

Brin introduced the geometric near-neighbor access tree(GNAT) indexing structure,which chooses k split points at the top level and each of the remaining feature vectors are associated with the closest split points.

GNAT is then built recursively and the parameter k is chosen to be a different value for each feature set depending on its cardinality.
