yuhao yang commented on SPARK-20082:
------------------------------------
I'm OK with only supporting initialModel for Online LDA now. For EM LDA, an
initial model is also possible, but we may need some extra check depending on
if EM can fit on new documents.
I'll make a pass on the current implementation. But we still need the opinion
and final check from [~josephkb] or other committers.
> 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: New Feature
> Components: ML
> Affects Versions: 2.1.0
> Reporter: Mathieu DESPRIEE
>
> 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.
