> In current implementation, each findSynonyms call will need to do a Euclidean Normalization (cosineVec / wordVecNorms), this is expensive. Caching a copy of normalized wordVectors will speed up multiple findSynonyms call. This is how the Google's word2vec C code implemented. 
> In addition, doing a lazy loading for wordVectors will be nice as well.
