论文摘要
尽管多视图学习在过去几十年中取得了显着的进步,但由于对不同观点之间的复杂相关性进行建模,尤其是在缺少的视图背景下,这仍然是具有挑战性的。为了应对挑战,我们提出了一个新颖的框架,称为跨部分多视图网络(CPM-NETS),该框架旨在充分和迅速利用多个部分视图。我们首先为多视图表示形式提供了正式的完整性和多功能性偏差,然后从理论上证明了学到的潜在表示的多功能性。为了完整性,通过模仿数据传输,可以将学习潜在多视图表示的任务特异性地转化为退化过程,从而隐含地可以实现一致性和互补性之间的最佳权衡。我们的模型配备了对抗策略,可以稳定地渗出丢失的视图,并从每个视图中编码每个样本的信息,以编码为潜在表示,以进一步提高完整性。此外,引入了非参数分类损失,以产生结构化表示并防止过度分化,从而赋予该算法在观察失误的情况下具有有希望的概括。广泛的实验结果验证了我们算法对现有艺术状态的有效性,用于分类,表示学习和数据插补。
Although multi-view learning has made signifificant progress over the past few decades, it is still challenging due to the diffificulty in modeling complex correlations among different views, especially under the context of view missing. To address the challenge, we propose a novel framework termed Cross Partial Multi-View Networks (CPM-Nets), which aims to fully and flflexibly take advantage of multiple partial views. We fifirst provide a formal defifinition of completeness and versatility for multi-view representation and then theoretically prove the versatility of the learned latent representations. For completeness, the task of learning latent multi-view representation is specififically translated to a degradation process by mimicking data transmission, such that the optimal tradeoff between consistency and complementarity across different views can be implicitly achieved. Equipped with adversarial strategy, our model stably imputes missing views, encoding information from all views for each sample to be encoded into latent representation to further enhance the completeness. Furthermore, a nonparametric classifification loss is introduced to produce structured representations and prevent overfifitting, which endows the algorithm with promising generalization under view-missing cases. Extensive experimental results validate the effectiveness of our algorithm over existing state of the arts for classifification, representation learning and data imputation.
