**TLDR:** A problem focused on strong recognition under imbalanced data distributions where some classes are abundant and others are scarce.

<p>Long-tailed recognition directly addresses the imbalance found in real-world datasets. Popular classes are represented with many examples, while rare classes are weakly learned and often become failure points. This structure is common in product catalogs, biological species classification, and security events. Training strategies therefore need to preserve not only global accuracy but also performance on the tail classes.</p>
