> FlinkML Quickstart Loading Data section example doesn't work as described
> -------------------------------------------------------------------------
>
> Key: FLINK-9664
> URL: https://issues.apache.org/jira/browse/FLINK-9664
> Project: Flink
> Issue Type: Bug
> Components: Documentation, Machine Learning Library
> Affects Versions: 1.5.0
> Reporter: Mano Swerts
> Assignee: Rong Rong
> Priority: Major
> Labels: documentation-update, machine_learning, ml,
> pull-request-available
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The ML documentation example isn't complete:
> [https://ci.apache.org/projects/flink/flink-docs-release-1.5/dev/libs/ml/quickstart.html#loading-data]
> The referred section loads data from an astroparticle binary classification
> dataset to showcase SVM. The dataset uses 0 and 1 as labels, which doesn't
> produce correct results. The SVM predictor expects -1 and 1 labels to
> correctly predict the label. The documentation, however, doesn't mention
> that. The example therefore doesn't work without a clue why.
> The documentation should be updated with an explicit mention to -1 and 1
> labels and a mapping function that shows the conversion of the labels.
