论文摘要
在许多图像处理方案中,多视图聚类具有广泛的应用程序。在这些情况下,原始图像数据通常包含缺失的实例和噪声,大多数多视图聚类方法都忽略了这一点。但是,缺失实例可能使这些方法很难直接使用,并且噪音将导致不可靠的聚类结果。在本文中,我们提出了一种新颖的自动加权嘈杂和不完整的多视图聚类框架(Animc),它通过软自动加权策略和双重柔软的常规回归模型。首先,通过设计自适应的半规则化的非负矩阵分解(自适应半RNMF),软自动加权策略为每种视图分配了适当的权重,并添加了一个软边界,以平衡噪声和不完整性的影响。其次,通过提出θ-Norm,通过选择不同的θ来调整模型的稀疏度。与现有方法相比,Animc具有三个独特的优势:1)在不同情况下调整我们的框架,从而提高其概括能力是一种软算法; 2)它会自动学习每个视图的适当重量,从而减少噪音的影响; 3)它执行双重的正则回归,该回归在不同的视图中与相同的实例保持一致,从而减少了缺失实例的影响。广泛的实验结果表明,其优于其他最先进方法的优势。
Multi-view clustering has wide applications in many image processing scenarios. In these scenarios, original image data often contain missing instances and noises, which is ignored by most multi-view clustering methods. However, missing instances may make these methods difficult to use directly and noises will lead to unreliable clustering results. In this paper, we propose a novel Auto-weighted Noisy and Incomplete Multi-view Clustering framework (ANIMC) via a soft auto-weighted strategy and a doubly soft regular regression model. Firstly, by designing adaptive semi-regularized nonnegative matrix factorization (adaptive semi-RNMF), the soft auto-weighted strategy assigns a proper weight to each view and adds a soft boundary to balance the influence of noises and incompleteness. Secondly, by proposingθ-norm, the doubly soft regularized regression model adjusts the sparsity of our model by choosing differentθ. Compared with existing methods, ANIMC has three unique advantages: 1) it is a soft algorithm to adjust our framework in different scenarios, thereby improving its generalization ability; 2) it automatically learns a proper weight for each view, thereby reducing the influence of noises; 3) it performs doubly soft regularized regression that aligns the same instances in different views, thereby decreasing the impact of missing instances. Extensive experimental results demonstrate its superior advantages over other state-of-the-art methods.
