kev-inn opened a new pull request #966: URL: https://github.com/apache/systemml/pull/966
This adds functionality for a federated recode transform. The resulting matrix will also be federated. Currently none of the other transform modes are supported and will result in failure (note: WIP). The decode works, but it is not a federated operation, instead the federated matrices are just sent back to the master and a local decode is executed. This is again is quite a large PR so an early look (@Baunsgaard ?) would be appreciated while I continue to adapt things to support other encodings. Federated decode will be done in a separate PR. I already added the initial privacy features, but @sebwrede you might want to take a closer look since the current recode implementation leaks all the distinct values of columns to the master which could be reason for another level of privacy. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
