[jira] [Created] (SYSTEMML-1965) Refactor nn layers to move the
computation in forward/backward function known at compile time to init
function
Niketan Pansare created SYSTEMML-1965:
-----------------------------------------
Summary: Refactor nn layers to move the computation in forward/backward function known at compile time to init function
Key: SYSTEMML-1965
URL: https://issues.apache.org/jira/browse/SYSTEMML-1965
Project: SystemML
Issue Type: Bug
Reporter: Niketan Pansare
Ideally, we should move the computation known at compile time to init layer, rather than keep in the forward function. This reduces recompilation time and also potentially unnecessary instructions. Here is an example snippet from our conv2d layer:
{code}
Hout = as.integer(floor((Hin + 2*padh - Hf)/strideh + 1))
Wout = as.integer(floor((Win + 2*padw - Wf)/stridew + 1))
{code}
[~prithvi_r_s] [~dusenberrymw] [~reinwald] do you have any comments or concerns ?
[~dusenberrymw] do you have free cycles to take this over ?
