We formulate two Kantorovich-like optimal transport problems by seeking to minimize the Choquet integral of the cost function with respect to either the reference set of joint belief functions or their dual plausibility functions. We give a noticeable application by choosing a metric as cost function: this permits to define pessimistic and optimistic Choquet-Wasserstein pseudo-distances, that can be used to compare belief functions on the same space.

This framework is designed to handle multiple data modalities, such as visual, audio, and text, frequently encountered in real-world applications. By integrating these different data types, this framework facilitates a more holistic understanding of information, thus improving the accuracy and reliability of retrieval tasks. One of the strengths of this framework is its ability to learn semantic relationships within and between modalities through advanced deep neural networks. These networks are trained on query-hit pairs generated from query logs. A major innovation of this approach lies in the efficient handling of multimodal data uncertainty through an improved fuzzy clustering technique. Additionally, the search process is refined through the use of triplet-loss Siamese networks for sophisticated reranking, as well as a novel fusion approach using the ordered weighted average (OWA) operator to combine the ranks of different retrieval systems. This framework leverages parallel processing and transfer learning for efficient feature extraction across different modalities, thus significantly improving scalability and adaptability. Performance has been rigorously evaluated through comprehensive testing on six widely recognized multimodal datasets. The results indicate that this integrated approach, which combines clustering ranking, triplet loss Siamese network for reranking, OWA-based fusion, and the alternative adaptive fuzzy means method (AAFCM) for soft clustering, consistently outperforms all previous configurations reported in the literature.

The task of optimal scale selection for multi-scale decision systems is an important issue in the field of granular computing research, especially when data are dynamically updated. However, analyzing multi-scale fuzzy ordered information with dominance-based rough fuzzy sets poses significant challenges, particularly when handling incomplete data, which is prevalent in real-world scenarios. Meanwhile, multi-granulation rough fuzzy sets are an effective extension of rough set that describes a target concept from multiple perspectives. To address these challenges and explore multi-scale decision systems based on multi-granulation rough sets, this paper proposes a novel framework that integrates dominance-based rough fuzzy sets and multi-granulation rough sets into the analysis of dynamic incomplete multi-scale fuzzy ordered information. Firstly, we introduce an incomplete generalized multi-scale fuzzy ordered decision system, defining granular information transformation functions as monotonically increasing functions. By employing an expanded dominance relation, we analyze the changes in dominating and dominated classes across different scales and propose two types of optimal scale combinations (OSCs) along with an algorithm to identify them. Secondly, we extend the model by incorporating dominance-based multi-granulation rough fuzzy sets, and introduce four additional OSC concepts to enhance the analysis from a multi-granulation perspective. Furthermore, to handle dynamic data environments, we investigate the impact of adding new objects on six types of OSCs and design algorithms to update them efficiently. Numerical experiments demonstrate the effectiveness and practical applicability of the proposed framework, highlighting its potential to address complex decision-making problems involving incomplete and multi-scale fuzzy ordered information.</div></div>","PeriodicalId":55130,"journal":{"name":"Fuzzy Sets and Systems","volume":"515 ","pages":"Article 109420"},"PeriodicalIF":3.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
