Dynamic embeddings

So far, all the embeddings we have considered have been static; that is, they are deployed as a dictionary of words (and subwords) mapped to fixed dimensional vectors. The vector corresponding to a word in these embeddings is going to be the same regardless of whether it is being used as a noun or verb in the sentence, for example the word "ensure" (the name of a health supplement when used as a noun, and to make certain when used as a verb). It also provides the same vector for polysemous words or words with multiple meanings, such as "bank" (which can mean different things depending on whether it co-occurs with the word "money" or "river"). In both cases, the meaning of the word changes depending on clues available in its context, the sentence. Dynamic embeddings attempt to use these signals to provide different vectors for words based on its context.
