---------------------------------
Summary: Incremental update of LDA model, by adding initialModel
as start point
Key: SPARK-20082
URL: https://issues.apache.org/jira/browse/SPARK-20082
Project: Spark
Issue Type: Wish
Components: MLlib
Affects Versions: 2.1.0
Reporter: Mathieu D
Some mllib models support an initialModel to start from and update it
incrementally with new data.
>From what I understand of OnlineLDAOptimizer, it is possible to incrementally
>update an existing model with batches of new documents.
I suggest to add an initialModel as a start point for LDA.
