[jira] [Assigned] (SPARK-19422) Cache input data in algorithms
[ https://issues.apache.org/jira/browse/SPARK-19422?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Apache Spark reassigned SPARK-19422:
------------------------------------
Assignee: (was: Apache Spark)
> Cache input data in algorithms
> ------------------------------
>
> Key: SPARK-19422
> URL: https://issues.apache.org/jira/browse/SPARK-19422
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 2.2.0
> Reporter: zhengruifeng
>
> Now some algorithms cache the input dataset if it was not cached any more {{StorageLevel.NONE}}:
> {{FeedForwardTrainer}}, {{LogisticRegression}}, {{OneVsRest}}, {{KMeans}}, {{AFTSurvivalRegression}}, {{IsotonicRegression}}, {{LinearRegression with non-WSL solver}}
> It maybe reasonable to cache input for others:
> {{DecisionTreeClassifier}}, {{GBTClassifier}}, {{RandomForestClassifier}}, {{LinearSVC}}
> {{BisectingKMeans}}, {{GaussianMixture}}, {{LDA}}
> {{DecisionTreeRegressor}}, {{GBTRegressor}}, {{GeneralizedLinearRegression with IRLS solver}}, {{RandomForestRegressor}}
> {{NaiveBayes}} is not included since it only make one pass on the data.
> {{MultilayerPerceptronClassifier}} is not included since the data is cached in {{FeedForwardTrainer.train}}
