But class weighting doesnt need recalibration, isnt?

Hello
I am having extremely imbalanced dataset and trying to find support for
class weights in hivemall ffm classifier in specific, however couldnt find
any mention in the docs.
Is this feature supported, otherwise i had to go with negative downsampling.
Please advise
Thank you
Hi Maktoto,
It seems priorities have been shifted a bit since our last discussion. I
was wondering if you have thoughts when the FFM prediction logic will
stabilize and get mature?
I am referring to this issue
https://issues.apache.org/jira/browse/HIVEMALL-24 which is planned to be
part of 0.5.2

Hello,
I am looking to use HiveMALL LR for CTR prediction on Criteo dataset.
I can find that LR + SGD is supported by default. Any idea how to use LR
along with FTRL or AdaGrad optimizer ?
Many Thanks
