> Project: Ignite
> Issue Type: Improvement
> Components: ml
> Reporter: Artem Malykh
> Assignee: Artem Malykh
> Priority: Minor
> Fix For: 2.8
>
>
> For now BaggingUpstreamTransformer makes upstream sequential to make
> transformation deterministic. Maybe we should do it other way, for example
> use mapping of the form (entryIdx, en) -> Stream.generate(() -> en).limit(new
> PoissonDistribution(Well19937c(entryIdx + seed), ...).sample())
