--------------------------------------
Summary: Word2VecModel.findSynonyms can spuriously reject the best
match when invoked with a vector
Key: SPARK-17548
URL: https://issues.apache.org/jira/browse/SPARK-17548
Project: Spark
Issue Type: Bug
Components: MLlib
Affects Versions: 2.0.0, 1.6.2, 1.5.2, 1.4.1
Environment: any
Reporter: William Benton
Priority: Minor
The `findSynonyms` method in `Word2VecModel` currently rejects the best match a
priori. When `findSynonyms` is invoked with a word, the best match is almost
certain to be that word, but `findSynonyms` can also be invoked with a vector,
which might not correspond to any of the words in the model's vocabulary. In
the latter case, rejecting the best match is spurious.
