> -----------------------------------------------------------------
>
> Key: SPARK-10105
> URL: https://issues.apache.org/jira/browse/SPARK-10105
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Reporter: Antonio Murgia
> Priority: Minor
> Labels: mllib, top-k, word2vec
>
> When training Word2Vec on a really big dataset, it's really hard to evaluate the right minCount parameter, it would really help having a parameter to choose how many words you want to be in the vocabulary.
> Furthermore, the original Word2Vec paper, state that they took into account the most frequent 1M words.
