LI Guobao closed SYSTEMML-2306. ------------------------------- > Implementation of a script with paramserv func > ---------------------------------------------- > > Key: SYSTEMML-2306 > URL: https://issues.apache.org/jira/browse/SYSTEMML-2306 > Project: SystemML > Issue Type: Sub-task > Reporter: LI Guobao > Assignee: LI Guobao > Priority: Major > Fix For: SystemML 1.2 > > > This task aims to write a dml script consisting the paramserv function. We > could easily reuse the MNIST LeNet example and adapt it by creating a > struct-like model and passing the update function as well as the aggregation > function. In this case, the update function which will be executed in workers > should consist of calculating the gradients by walking the batch forward and > backward steps. And the aggregation function which will be runned in > parameter server should consist of updating the weights and biases by > aggregating the received gradients. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
