-----------------------------------
Summary: Save and expose "in bag" tracking for random forest model
Key: SPARK-23730
URL: https://issues.apache.org/jira/browse/SPARK-23730
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 2.3.0
Reporter: Julian King
In a random forest model, it is often useful to be able to keep track of which
samples ended up in each of the bootstrap replications (and how many times this
happened). For instance, in the R randomForest package this is accomplished
through the option keep.inbag=TRUE
Similar functionality in Spark ML's random forest would be helpful
