yuhao yang created SPARK-7089: --------------------------------- Summary: Introduce LDAOptimizer to LDA to improve extensibility Key: SPARK-7089 URL: https://issues.apache.org/jira/browse/SPARK-7089 Project: Spark Issue Type: Improvement Components: MLlib Affects Versions: 1.3.1 Reporter: yuhao yang
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
