A trail-maintenance desk can start from a checkpoint trained on outdoor-incident notes or from one trained on restaurant reviews. Both are called pretrained. Which source is the better first transfer experiment, and why?
Select an answer to reveal the explanation.
Short Explanation
Both checkpoints are pretrained, but they are not interchangeable. Outdoor-incident notes sit closer to trail maintenance than restaurant reviews, so measure that source first. “Pretrained” does not erase domain distance, and an NCCL mesh is not the selection rule.
Full Explanation
Two pretrained checkpoints are not interchangeable as transfer sources. A model whose pretraining domain sits nearer the target task — here, outdoor-incident notes versus restaurant reviews — is the stronger first arm in a transfer comparison. Domain distance is the reason; “pretrained” alone does not erase it. Food-text density and collective meshes are not the selection rule.
