Re: [Kaldi-users] Weight Pushing

Essentially graph building process makes sure that the resulting graph is
"stochastic" and scripts print stochasticity so that you can monitor it.

Hi Dan,

I read about avoiding weight pushing in the Kaldi website but I couldn't
find which stage of the graph creation compensates for that.  

My question is How to make them pushed without pushing? and What stage of
graph creation (C++ binary) does it?

 

Thanks,

Lahiru

It's not an encoding change, it's a change in the graph creation
algorithm so the weights are "already pushed".  It has no effect on
the graph size.  The quality should be the same in general (although
it will be better under some almost-pathological cases).  It means
that you don't have to worry about weight pushing failing.
