> KNN and SVM algorithms don't work when partition doesn't contain data
> ---------------------------------------------------------------------
>
> Key: IGNITE-8233
> URL: https://issues.apache.org/jira/browse/IGNITE-8233
> Project: Ignite
> Issue Type: Bug
> Components: ml
> Affects Versions: 2.5
> Reporter: Anton Dmitriev
> Assignee: Anton Dmitriev
> Priority: Major
> Fix For: 2.5
>
>
> KNN and SVM algorithms implemented with assumption that partition data won't
> be null:
> {code:java}
> public LabeledDataset(double[][] mtx, double[] lbs, String[] featureNames,
> boolean isDistributed) {
> super();
> assert mtx != null;
> assert lbs != null;
> {code}
> Currently it's wrong assumption, so we need to update dataset to support this
> assumption or update these algorithms.
