Checkpoint
Answer in brief
A checkpoint is a saved copy of the training state, written during a run so that the run can resume or be rolled back.
Checkpoint in practice
Checkpoints turn a late failure from a lost run into a few lost minutes. They are also what you keep at the end.
They cost storage for as long as they exist. Keep the last few and the best, and put them on storage that survives the machine.
