Adaptive Weighted LSSVM for Multi-View Classification
This addresses multi-view classification, an incremental improvement for kernel-based methods with potential privacy benefits.
The paper tackles the problem of multi-view classification by proposing AW-LSSVM, an adaptive weighted LS-SVM that promotes complementary learning through iterative global coupling. Experiments show it outperforms existing kernel-based multi-view methods on most datasets while keeping raw features isolated for privacy-preserving scenarios.
Multi-view learning integrates diverse representations of the same instances to improve performance. Most existing kernel-based multi-view learning methods use fusion techniques without enforcing an explicit collaboration type across views or co-regularization which limits global collaboration. We propose AW-LSSVM, an adaptive weighted LS-SVM that promotes complementary learning by an iterative global coupling to make each view focus on hard samples of others from previous iterations. Experiments demonstrate that AW-LSSVM outperforms existing kernel-based multi-view methods on most datasets, while keeping raw features isolated, making it also suitable for privacy-preserving scenarios.
