融合多视图与图嵌入的随机向量链接模型,提升分类泛化能力。

GRVFL-MV: Graph Random Vector Functional Link Based on Multi-View Learning

  • 基于多视图学习和图嵌入,融合数据几何结构
  • 在27个UCI、KEEL及多个图像数据集上表现更优
  • 适合处理具有复杂结构的多源数据分类任务

随机向量功能链接(RVFL)作为一种随机神经网络,其分类性能已广受认可。然而,由于其浅层学习特性,RVFL常无法充分利用数据集中的全部相关信息,并忽略数据的几何性质。为解决上述问题,本文提出一种基于多视图学习的图随机向量功能链接模型(GRVFL-MV)。该模型在多个视图上训练,结合多视图学习(MVL)思想,并通过图嵌入(GE)框架引入所有视图的几何属性。融合RVFL、MVL与GE框架使模型具备:i)高效学习能力——利用RVFL拓扑结构,有效捕捉多视图数据中的非线性关系,实现高效精准预测;ii)全面表征能力——融合多视角信息增强模型对复杂模式与关系的捕捉能力,提升整体泛化性能;iii)结构感知能力——通过GE框架自然利用数据内在与惩罚子空间学习准则,保留原始数据分布。在27个UCI与KEEL数据集、50个Corel5k数据集及45个AwA数据集上的评估表明,该模型显著优于基线模型,展现出更强的跨数据集泛化能力。

原文摘要 · Abstract (English)

The classification performance of the random vector functional link (RVFL), a randomized neural network, has been widely acknowledged. However, due to its shallow learning nature, RVFL often fails to consider all the relevant information available in a dataset. Additionally, it overlooks the geometrical properties of the dataset. To address these limitations, a novel graph random vector functional link based on multi-view learning (GRVFL-MV) model is proposed. The proposed model is trained on multiple views, incorporating the concept of multiview learning (MVL), and it also incorporates the geometrical properties of all the views using the graph embedding (GE) framework. The fusion of RVFL networks, MVL, and GE framework enables our proposed model to achieve the following: i) efficient learning: by leveraging the topology of RVFL, our proposed model can efficiently capture nonlinear relationships within the multi-view data, facilitating efficient and accurate predictions; ii) comprehensive representation: fusing information from diverse perspectives enhance the proposed model's ability to capture complex patterns and relationships within the data, thereby improving the model's overall generalization performance; and iii) structural awareness: by employing the GE framework, our proposed model leverages the original data distribution of the dataset by naturally exploiting both intrinsic and penalty subspace learning criteria. The evaluation of the proposed GRVFL-MV model on various datasets, including 27 UCI and KEEL datasets, 50 datasets from Corel5k, and 45 datasets from AwA, demonstrates its superior performance compared to baseline models. These results highlight the enhanced generalization capabilities of the proposed GRVFL-MV model across a diverse range of datasets.
