Addressing this gap, De-Chuan Zhan and his team at LAMDA, Nanjing University, have introduced innovative research in the field of Multi-dimensional Classification, published in Frontiers of Computer Science, which is co-published by Higher Education Press and Springer Nature.
The researchers highlight the importance of considering dimension-wise metrics in real-world MDC scenarios and have introduced two specific metrics aimed at this. They also noted imbalanced class distributions within each labeling dimension and developed a novel Imbalance-Aware Fusion Model (IMAM) to tackle these challenges.
The IMAM approach initially separates the task into various multi-class classification challenges, each tailored to a specific dimension. This allows the development of imbalance-aware deep models that maintain robust performance across all dimensions without compromising on individual accuracy. Additionally, the IMAM method utilizes dimension-specific models to serve as multiple teachers, transferring their knowledge to a comprehensive student model that integrates all dimensions.
Comprehensive testing on diverse MDC datasets has shown that the IMAM method significantly outperforms existing models, bridging a considerable performance gap.
