Key Points

To provide a comprehensive and critical review of learning from imbalanced data, examining core theoretical challenges, existing algorithmic solutions, evaluation metrics, and future research opportunities.
Reviewed theoretical and practical challenges associated with learning under severe class distribution skews and underrepresented data in large-scale networked systems.
Evaluated state-of-the-art technological approaches and performance assessment metrics designed specifically for imbalanced learning scenarios.
Demonstrated that standard machine learning algorithms experience significant performance degradation when processing severely skewed class distributions without specialized intervention.
Identified critical limitations in conventional evaluation metrics, underscoring the necessity of specialized assessment measures for rare-class detection.
Synthesized key research directions and open opportunities for developing robust algorithms and knowledge representations in data-intensive domains.
