[GitHub] [systemds] phaniarnab opened a new pull request, #1623: [SYSTEMDS-3367] Integrate UDF encoders in task graph

phaniarnab opened a new pull request, #1623:
URL: https://github.com/apache/systemds/pull/1623

   This patch integrates UDF-based transformencoders into the
   task graph to allow concurrent execution. As we cannot estimate
   the sparsity of an arbitrary UDF output, we always allocate
   dense output matrix if at least one UDF is present. If an UDF
   comes after a dummycode, we slice the expanded columns and
   apply the UDF. Moreover, we disable row partitioning for UDFs.
