-----------------------------------
Summary: Paramserv low accuracy with EPOCH update frequency
Key: SYSTEMML-2406
URL: https://issues.apache.org/jira/browse/SYSTEMML-2406
Project: SystemML
Issue Type: Bug
Reporter: LI Guobao
Assignee: LI Guobao
In the EPOCH update strategy, we should aggregate the gradients generated after
the local model updating and push them when each epoch finishes. Otherwise, the
intermediate gradients will be lost after each local model updating and at
last, the global model will be updated with only the gradients of last
iteration.
