A bellows shop records a shop-only pressure trace that no pretrained stills or speech model has ever seen. What is the honest call?
Select an answer to reveal the explanation.
Short Explanation
If no pretrained cousin has ever seen that pressure squiggle, transfer is wishful thinking. Build a small honest head for the new signal instead of forcing a picture ear onto a gauge.
Full Explanation
Transfer fails when the source model’s modality and domain cannot observe the new signal. A shop-only pressure trace is outside stills and speech pretraining, so a small from-scratch head is the honest budget. Scale and mismatched modality reuse do not fix that gap.
