---------------------------------
Summary: Online Variational Inference for the Hierarchical
Dirichlet Process
Key: SPARK-8555
URL: https://issues.apache.org/jira/browse/SPARK-8555
Project: Spark
Issue Type: Bug
Components: MLlib
Reporter: yuhao yang
Priority: Minor
The task is created for exploration on the online HDP algorithm described in
http://jmlr.csail.mit.edu/proceedings/papers/v15/wang11a/wang11a.pdf.
Major advantage for the algorithm: one pass on corpus, streaming friendly,
automatic K (topic number).
Currently the scope is to support online HDP for topic modeling, i.e. probably
an optimizer for LDA.
