Further, trying to be more specific about checkpoint with R, I may suggest the following readings. Look for "checkpoint models" in: http://h2o-release.s3.amazonaws.com/h2o/rel-tibshirani/8/docs-website/h2o-docs/booklets/DeepLearning_Vignette.pdf Look for "checkpointing" in: https://github.com/h2oai/h2o-training-book/blob/master/hands-on_training/deep_learning.md However, that is not exactly what you asked for. -- GG [[alternative HTML version deleted]]
