----------------------------------------
Summary: LDA should handle empty documents
Key: SPARK-5562
URL: https://issues.apache.org/jira/browse/SPARK-5562
Project: Spark
Issue Type: Test
Components: MLlib
Affects Versions: 1.3.0
Reporter: Joseph K. Bradley
Priority: Minor
Latent Dirichlet Allocation (LDA) could easily be given empty documents when
people select a small vocabulary. We should check to make sure it is robust to
empty documents.
This will hopefully take the form of a unit test, but may require modifying the
LDA implementation.
