Joseph K. Bradley updated SPARK-9658:
-------------------------------------
Summary: ML QA: API: Binary incompatible changes in 1.5 (was: Binary
incompatible changes in MLlib 1.5)
> ML QA: API: Binary incompatible changes in 1.5
> ----------------------------------------------
>
> Key: SPARK-9658
> URL: https://issues.apache.org/jira/browse/SPARK-9658
> Project: Spark
> Issue Type: Sub-task
> Components: ML, MLlib
> Affects Versions: 1.5.0
> Reporter: Xiangrui Meng
> Assignee: Xiangrui Meng
> Priority: Blocker
>
> Generated a list of binary incompatible changes using MiMa and filter out
> some false positives:
> 1. LDA.docConcentration
> It will be nice to keep the old APIs unchanged. For example, we can use
> “asymmetricDocConcentration”. Then “getDocConcentration" would return the
> first item if the concentration vector is a constant vector.
> 2. LDAModel.gammaShape / topicConcentration
> Should be okay if we assume that no one extends LDAModel.
> 3. Params.setDefault
> If we have time to investigate this issue. We should put it back.
> 4. LogisticRegressionModel.threshold is missing.
> 5. LogisticRegression.setThreshold shouldn't be in the Params trait. We need
> to override it anyway.
> Will create sub-tasks for each item.
