-------------------------------------
Assignee: Ruifeng Zheng
> Avoid serializing FeedForwardModel scratch buffers
> --------------------------------------------------
>
> Key: SPARK-59313
> URL: https://issues.apache.org/jira/browse/SPARK-59313
> Project: Spark
> Issue Type: Sub-task
> Components: ML
> Affects Versions: 5.0.0
> Reporter: Ruifeng Zheng
> Assignee: Ruifeng Zheng
> Priority: Major
> Labels: pull-request-available
>
> FeedForwardModel lazily allocates outputs and deltas as reusable scratch
> buffers for forward and gradient computations. Mark them transient because
> they can be recreated after deserialization and otherwise cached batch
> matrices are unnecessarily serialized with the model.
