A coach-painter already has a pretrained stills model that nearly matches shop pigments. They can adapt a small last stage or retrain every weight. Which choice is the official less-computation path when the source is close?
Select an answer to reveal the explanation.
Short Explanation
When the pretrained palette is already close, a light last-stage touch-up beats a full retrain. Save the heavy compute for when the source domain is clearly wrong.
Full Explanation
A small transfer update is the official less-computation path when the source model is already close to the target. Full retrain is reserved for evidence that the source domain is wrong. Invented products are not Performance Optimization levers on this exam.
