About the impact of grouping classes in multiclass classification [D]
Addressing data scarcity in multiclass classification is a common challenge. Grouping infrequent classes into a "catch-all" category, like "Other breed" in dog breed classification, can introduce complexities. While seemingly pragmatic, this approach may force models to learn convoluted decision boundaries, potentially hindering overall performance. An alternative—and often more effective—strategy involves treating these instances as out-of-distribution samples, focusing training data on well-represented classes. Consider "Trained an diffusion model that runs on 264KB of RAM," demonstrating innovative approaches to resource constraints in AI.
