> Word2Vec: avoid intermediate representation when creating model
> ---------------------------------------------------------------
>
> Key: SPARK-7045
> URL: https://issues.apache.org/jira/browse/SPARK-7045
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.4.0
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> Word2VecModel now stores the word vectors as a single, flat array; Word2Vec
> does as well. However, when Word2Vec creates the model, it builds an
> intermediate representation. We should skip that intermediate representation.
> However, it will be nice to create a public constructor for Word2VecModel
> which takes that intermediate representation (a Map from String words to
> their Vectors), since it's a user-friendly representation.
