yuhao yang updated SPARK-7090: ------------------------------ Summary: Introduce LDAOptimizer to LDA to improve extensibility (was: Introduce LDAOptimizer to LDA to improve extensibility) > Introduce LDAOptimizer to LDA to improve extensibility > ------------------------------------------------------- > > Key: SPARK-7090 > URL: https://issues.apache.org/jira/browse/SPARK-7090 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 1.3.1 > Reporter: yuhao yang > Original Estimate: 72h > Remaining Estimate: 72h > > LDA was implemented with extensibility in mind. And with the development of > OnlineLDA and Gibbs Sampling, we are collecting more detailed requirements > from different algorithms. > As Joseph Bradley proposed in https://github.com/apache/spark/pull/4807 and > with some further discussion, we'd like to adjust the code structure a little > to present the common interface and extension point clearly. > Basically class LDA would be a common entrance for LDA computing. And each > LDA object will refer to a LDAOptimizer for the concrete algorithm > implementation. Users can customize LDAOptimizer with specific parameters and > assign it to LDA. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
