A machine learning practitioner is seeking insights on the impact of grouping classes in multiclass classification, particularly when dealing with datasets that have a long tail of underrepresented classes. The user proposes an example of classifying dog breeds, where rare breeds might be consolidated into an 'Other breed' category. This approach raises concerns about forcing the model to learn complex decision boundaries and potentially misinterpreting the 'other' category as an out-of-distribution detection problem. AI
IMPACT Explores a nuanced aspect of classification model training, potentially impacting how underrepresented data is handled.
