However, the potential of these approaches may be limited due to VAE's mediocre generation capability or GAN's well-known instability during adversarial training. In contrast, denoising diffusion probabilistic models (DDPMs) represent a new and promising class of generative models that may unlock fresh dimensions in clustering. In this study, we introduce an innovative expectation-maximization (EM) framework for clustering using DDPMs. In the E-step, we aim to derive a mixture of Gaussian priors for the subsequent M-step. In the M-step, our focus lies in learning clustering-friendly latent representations for the data by employing the conditional DDPM and matching the distribution of latent representations to the mixture of Gaussian priors. We present a rigorous theoretical analysis of the optimization process in the M-step, proving that the optimizations are equivalent to maximizing the lower bound of the Q function within the vanilla EM framework under certain constraints. Comprehensive experiments validate the advantages of the proposed framework, showcasing superior performance in clustering, unsupervised conditional generation and latent representation learning.

Due to the complexities involved in data acquisition and alignment, practical challenges such as the Partially View-unaligned Problem (PVP) and the Partially Sample-missing Problem (PSP) may emerge, and the multi-view problem with incomplete information when both coexist. Current research primarily focuses on solving PVP or PSP individually. Although there is a method that can handle PVP and PSP simultaneously, it relies on traditional Euclidean distance to compute cross-view distance matrices. This separation of matrix computation and network training hinders achieving globally optimal optimization matrices and fails to capture the consistency and complementarity between views adequately. To overcome these challenges, the Cross-View Alignment and Completion for Incomplete Information Multi-View Clustering (CAC-MVC) is proposed. In brief, CAC-MVC integrates a contrastive optimization module to improve the consistency between feature representation and alignment tasks. In addition, a module based on category-level alignment and completion strategy is designed to establish optimal alignment and completion relationships between views. Our experiments on four datasets, alongside comparisons with over 10 state-of-the-art approaches, demonstrate the effectiveness and robustness of CAC-MVC in multi-view clustering with incomplete information.</div></div>","PeriodicalId":51063,"journal":{"name":"Information Sciences","volume":"720 ","pages":"Article 122515"},"PeriodicalIF":8.1,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
