     [ https://issues.apache.org/jira/browse/FLINK-1746?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chesnay Schepler closed FLINK-1746.
-----------------------------------
    Resolution: Won't Do

Closing since flink-ml is effectively frozen.

> Linear discriminant analysis (LDA) [1] is used for dimensionality reduction prior to classification. But it can also be used to calculate a linear classifier on its own. Since dimensionality reduction is an important preprocessing step, a distributed LDA implementation is a valuable addition to flink-ml.
