  • 构建带图嵌入的多视图随机向量网络,融合局部判别加权结构
  • 采用非对称有界损失函数,有效抑制大误差残差影响
  • 适合需要高鲁棒性多源数据分类的场景,如图像与文本融合

随机向量函数链接(RVFL)网络为分类任务提供高效的随机学习框架。现有方法虽利用多视图互补信息,但难以保留视图特有的几何结构、限制大预测残差的影响以及建模多视图间关系。本文提出残差耦合图嵌入多视图RVFL模型结合灵活守护损失(XGRVFL-MV)。该模型为每视图构建RVFL表示,通过局部费雪判别分析加权方案构建内在与惩罚图以实现图嵌入,并采用有界且非对称的灵活守护(XG)损失进行残差学习。引入残差耦合项,促进各视图预测残差的一致性,同时保持视图特异性表示。优化问题通过基于Nesterov加速梯度的无逆一阶优化方法求解。在UCI、KEEL、AwA和Corel5k基准数据集上评估,实验结果与统计分析表明,该模型在多个基准数据集上性能优于基线方法。

原文摘要 · Abstract (English)

Random Vector Functional Link (RVFL) networks provide an efficient randomized learning framework for classification. Existing multi-view RVFL methods utilize complementary information from multiple views. However, preserving view-specific geometric structure, limiting the influence of large prediction residuals, and modeling relationships between multiple views remain challenging. This paper proposes a Residual-Coupled Graph-Embedded Multi-View RVFL model with fleXi guardian loss (XGRVFL-MV) for multi-view classification. The proposed model constructs RVFL representation for each view, incorporates graph embedding with intrinsic and penalty graphs constructed using the Local Fisher Discriminant Analysis weighting scheme. It also uses the bounded and asymmetric FleXi Guardian (XG) loss for residual learning. A residual-coupling term is introduced to encourage consistency among view-specific prediction residuals while preserving view-specific representations. The resulting optimization problem is solved using an inversion-free first-order optimization procedure based on Nesterov accelerated gradient descent. We evaluate the proposed model on UCI, KEEL, AwA, and Corel5k benchmark datasets. Experimental results, together with statistical analyses and hyperparameter sensitivity analyses, show that XGRVFL-MV achieves competitive classification performance compared with the baseline methods across the evaluated benchmark datasets.
