2. (mathematics) A map which, in any of several technical senses, represents the containment of one structure inside another.

   2. (differential topology) An immersion which is also a topological embedding; equivalently, a diffeomorphism whose image is a submanifold of its codomain.
   3. (field theory, Galois theory) A ring homomorphism between fields (the name deriving from the fact that all such maps are injective).
   4. (mathematical analysis) A map between metric spaces which preserves distances up to some scaling factor (called the distortion).

     “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.
