Furthermore, they often rely on single-scale fusion schemes, which can lead to the loss of critical semantic information. To address these challenges, we propose an Expert Knowledge-Guided Multi-granularity Multi-scale fusion framework for weakly-supervised histological segmentation, which leverages fine-grained text representations and multi-scale label-pixel fusion and alignment to suppress redundancy and strengthen supervision. Specifically, to address the interference of redundant text on homogeneous pixels, we start by constructing an expert knowledge-guided fine-grained text representation paradigm, progressively refining and extracting key information to uncover the multi-level clues and semantic features of the images. To effectively represent and convey fine-grained guidance knowledge, a multi-scale label-pixel fusion and alignment module is proposed, which emphasizes the fusion and interaction between fine-grained text prompts and image features, enhancing category sensitivity. Additionally, a visual state-space adaptive layer is embedded into a multi-stage pre-trained transformer encoder to improve long-range dependency modeling with low computational cost.

This study introduces a novel consensus-based ranking approach tailored for large-scale rating datasets, incorporating cluster analysis, multi-attribute decision-making (MADM), and a consensus-reaching mechanism. Initially, a rating matrix is constructed to consolidate the extensive rating data. Subsequently, cluster analysis segments the vast user base, and MADM is leveraged to produce group-specific rankings. Ranking aggregation technique is then applied to synthesize the rankings from disparate user groups into a unified collective ranking. Ultimately, a consensus-reaching process, which accounts for both intra-cluster and inter-cluster agreement, refines the ranking to ensure a harmonized consensus among all user groups.

Although information fusion is of great significance for GDM, there are still significant deficiencies in existing research within the framework of multi-scale information systems (MSIS). In particular, there is an urgent need to address the challenges of dealing with multi-structural data and managing the complex behaviors of decision-makers (DMs). Firstly, a novel concept, the heterogeneous multi-scale information system (HMSIS), is put forward. This system innovatively integrates utility value quantification analysis, fuzzy preference relation modeling, preference ranking algorithms, and equivalence class partitioning techniques, thereby constructing a highly realistic simulation framework for real-world data. Through this cross-paradigm data integration approach, the HMSIS provides a more adaptable and scalable theoretical foundation for GDM, effectively resolving the limitations of traditional models in handling complex data structures. Building on this foundation, this paper further develops the consensus-trust multi-network opinion interaction mechanism. This mechanism shatters the constraints of one-way information transmission in traditional decision-making processes. By devising an adaptive opinion exchange protocol, it enables multi-round and multi-dimensional information interactions among decision-makers. Additionally, innovative behavior monitoring and intervention rules are introduced, which can detect irrational behaviors of DMs, such as overconfidence and non-cooperation, in real time. Through dynamic weight adjustment, intelligent guidance strategies, and other means, targeted management is implemented to ensure the stability and effectiveness of the group decision-making process. Moreover, this paper constructs an optimized consensus reaching process (CRP). By embedding an optimization model and under the intelligent regulation of a virtual decision-making coordinator, it optimizes both the efficiency of decision-making information transmission and the accuracy of opinion convergence simultaneously. With the core objectives of minimizing the decision adjustment distance and shortening the consensus-reaching time, and combined with a dynamic weight allocation algorithm, this model achieves efficient and fair consensus building in complex decision-making environments. Finally, empirical studies conducted on a real-world dataset demonstrate the remarkable superiority of the proposed method. The experimental results further validate the method’s robust performance in handling heterogeneous data and complex decision-making scenarios.</div></div>","PeriodicalId":50367,"journal":{"name":"Information Fusion","volume":"125 ","pages":"Article 103401"},"PeriodicalIF":14.7,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515705","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}

Spatial domain identification is a fundamental step in spatial omics analysis, as it facilitates the delineation of functional tissue regions. However, most existing methods are tailored for single omic data and face substantial limitations when extended to spatial multi-omics contexts. Integrating consistent and complementary signals across multiple omics within spatially structured data remains a key challenge. In this study, we propose SpaMICS, a deep subspace learning framework designed for spatial domain identification from spatial multi-omics data. SpaMICS captures spatial dependencies and latent inter-spot relationships to learn high-level representations for each omic. To enhance information integration, we introduce a subspace learning module that explicitly disentangles consistent and complementary information across omics. Furthermore, we incorporate dual constraints to enhance information extraction: a low-rank constraint to emphasize consistent information across omics and a discriminative constraint that facilitates the extraction of complementary information. Extensive experiments on five real-world spatial multi-omics datasets, including spatial transcriptomics–proteomics and spatial transcriptomics–epigenomics data, demonstrate that SpaMICS consistently outperforms existing approaches, effectively integrating multi-omics data for accurate spatial domain identification.</div></div>","PeriodicalId":50367,"journal":{"name":"Information Fusion","volume":"125 ","pages":"Article 103428"},"PeriodicalIF":14.7,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515819","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}

This strategy ensures comprehensive global modeling while precisely capturing local spatial dependencies. Additionally, an unsupervised dominant view mining mechanism is introduced to dynamically identify the most discriminative perspectives prior to the feature fusion process, coupled with optimized alignment among views and consistent similarity distributions between nodes, aiming to mitigate inter-view information imbalance.

That is, feature selection and design of a stopping mechanism can be unified in the fuzzy concept-cognitive learning framework. Furthermore, by integrating the uncertainties of set approximation of clue based fuzzy reasoning and clue based fuzzy concept-cognitive learning for stopping samples at appropriate nodes, it significantly enhances the performance of the proposed hierarchical classifier.

Due to the complexity of IoMT network traffic and the high volume of data, advanced methods are necessary to enhance the security and reliability of these networks.
