embedding — Dizionario inglese

Sostantivo

1. The act or process by which one thing is embedded in another.

2. A map which, in any of several technical senses, represents the containment of one structure inside another. A continuous map which is also a homeomorphism between its domain and its image (considered with the subspace topology induced by its codomain).

3. A map which, in any of several technical senses, represents the containment of one structure inside another. An immersion which is also a topological embedding; equivalently, a diffeomorphism whose image is a submanifold of its codomain.

4. A map which, in any of several technical senses, represents the containment of one structure inside another. A ring homomorphism between fields (the name deriving from the fact that all such maps are injective).

5. A map which, in any of several technical senses, represents the containment of one structure inside another. A map between metric spaces which preserves distances up to some scaling factor (called the distortion).

6. A map which, in any of several technical senses, represents the containment of one structure inside another. An injective morphism in a concrete category which is also initial.

7. A representation of a unit of text (such as a word or token) as a vector, which encodes the context in which it is used.

   “A major reason we chose to study word embeddings is that they have been spectacularly successful in the last few years in helping computers make sense of language,” said Arvind Narayanan, a computer scientist at Princeton University and the paper’s senior author.

   A few years ago, Dr. [Alexander] Huth noticed that particular pieces of these maps — so-called context embeddings, which capture the semantic features, or meanings, of phrases — could be used to predict how the brain lights up in response to language.
