The dimension (width) of an embedding vector
Retrieves the embedding for this word, if it exists in the map
Retrieves the embedding for this word; if it doesn't exist in the map uses the unknown embedding instead.
Retrieves the embedding for this word; if it doesn't exist in the map uses the unknown embedding instead. That embedding is defined in the vector file. If it is needed, but doesn't exist, a RuntimeException is thrown.
Returns all keys presented in the map, excluding the key for the unknown token
Save this object in binary format.
The embedding corresponding to the unknown token
Basic functionality required by all implementations of word embeddings
