A face image dataset contains far fewer examples for one age group than others. What pre-training concern does this raise?

Choose the Best Answer

The issue can be evaluated from aggregate accuracy before labels or facets are reviewed. The concern is limited to post-training evaluation because representation cannot be assessed before fitting. The imbalance is irrelevant if the images are stored in the same object bucket. The model may learn weaker representations for the underrepresented group or overfit its few examples.
