Matthew Hayes updated DATAFU-149:
---------------------------------
Fix Version/s: (was: 1.6.0)
> Add MutliLabelStratifiedSample to DataFu.spark
> ----------------------------------------------
>
> Key: DATAFU-149
> URL: https://issues.apache.org/jira/browse/DATAFU-149
> Project: DataFu
> Issue Type: Improvement
> Affects Versions: 1.5.0
> Reporter: Russell Jurney
> Assignee: Russell Jurney
> Priority: Major
> Labels: datafu, spark
>
> I'm working on an implementation of On the Stratification of Multi-Label
> Data, to create a stratified (balanced, in my case) sample of highly skewed
> labels for a multi-label, multi-class classification problem. This isn't
> straightforward because adding one record adds multiple labels to the
> balance. A greedy algorithm that adds labels with the least common labels
> works, and since I'm writing it, it would probably make a good feature.
