-----------------------------------
Summary: 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
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.
