The face-periocular cross-modality matching (FPCM) provides a versatile solution, especially when traditional face recognition systems encounter challenges due to occlusions or the presence of sunglasses, which can obscure the periocular region, rendering it less effective in periocular recognition systems. This paper introduces a novel approach based on attention-aware ensemble learning (AEL) to address these challenges. This notion is embodied in AELNet, which features an attention-aware shared-parameter encoder and multiple classifier heads. AELNet is designed to harness the complementary features of the face and periocular regions, enhancing the quality of joint embeddings. A key aspect of AELNet is its ability to foster diversity among the classifier heads through unique embedding techniques and batch sampling strategies, ultimately boosting FPCM performance. We demonstrate the effectiveness of the AELNet by conducting extensive experiments on five unconstrained periocular-face datasets as a benchmark.

The changing fuzzy environmental factors and the hesitant psychology during the dynamic period commonly involve potential historical impacts of decisions and dynamic fuzzy intercorrelation. Quantitative indicators of attribute importance derived from fuzzy measures can account for intercorrelation but cannot ensure the dynamic feedback of historical decisions. For these reasons, the existing fuzzy decision-making methods have failure and poor stability when dealing with complex, hesitant dynamic fuzzy decision-making problems. Therefore, this paper aims to construct a dynamic decision-making model within the q-rung orthopair hesitant fuzzy(q-ROHF) environment. First, this paper derives the q-ROHF cross-entropy and four combinations of entropy formulas to derive the calculation method for the fuzzy measure of dynamic attributes. The Banzhaf value is used as a weighting metric to quantify the degree of impact of dynamic attributes to the decision result. Second, based on the Banzhaf value, a dynamic weighting algorithm incorporating a historical feedback mechanism and dynamic intercorrelation is proposed. Further, this paper derives a fuzzy preference relation(FPR) using the q-ROHF generalized fuzzy distance and presents an algorithm for updating the dynamic FPR matrix. Finally, a dynamic FPR-based AQM method is used to construct the dynamic decision-making model. The feasibility and effectiveness of the decision-making model in response to changing complex factors are demonstrated through two distinct real-world cases. Through robustness analysis and advantage analysis, it has been verified that the model exhibits superior dynamic decision-making stability and hesitant decision-making stability compared to existing models. The model can be a powerful tool for dealing with dynamic decision-making problems that involve hesitation and uncertainty.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"175 ","pages":"Article 113036"},"PeriodicalIF":7.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746206","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}

Nowadays, modularity and its variants are the most popular community quality evaluation metric applied in the detection of community structures. However, these modularity-based methods rarely consider higher-order structural information such as motifs in a network, which may lead to an incomplete and inaccurate understanding of the network. While some motif-based methods have been proposed, they suffer from resolution limitations and completely ignore lower-order structures. To bridge this gap and address community detection problem from a more hybrid view focusing on both lower-order and higher-order structures, this paper first proposes an adaptive hybrid-order modularity optimization function termed as TE-Modularity, which harmonizes triangle motif and edge information. It transcends traditional modularity by considering both lower-order and higher-order structures and can be applicable to all types of networks. In addition, we design a memetic algorithm called TE-MA, that uses TE-Modularity as the objective function to solve the community detection problem. A novel mutation operator based on triangle motifs is proposed, which can effectively accelerate the convergence of the proposed algorithm. Furthermore, we develop a new multipoint local search strategy, striking a good balance between the efficiency and quality of the algorithm.

However, many deep learning approaches for multi-source RS classification rely heavily on abundant labeled data, which can be time-consuming and often impractical. To address the limitations in feature extraction and classification accuracy stemming from the scarcity of labeled multi-source RS image samples in complex scenes, we propose a novel semi-supervised multi-source RS image classification network based on adaptive pseudo-label generation (S2CNet-APG). This framework incorporates attention modules that effectively embed active RS features into HS features, enhancing performance through squeezing and excitation (SE) driven attention mechanisms. Our semi-supervised learning approach employs adaptive thresholds to manage the quantity of pseudo-labels derived from unlabeled samples, while maintaining the spatial consistency of the information to ensure quality. This dual strategy effectively balances the quantity and quality of pseudo-labels, enabling accurate classification with limited labeled samples and transitioning multi-source RS image classification from a supervised to a semi-supervised paradigm.

Not only does this paradigm lead to inefficient methods, but it also makes the methods vulnerable to noisy data. Furthermore, this processing paradigm ignores the potential multi-granularity information in the data, which may lead to an incomplete understanding of the intrinsic relations and patterns of the data. To further improve the performance of outlier detection, multi-granular-ball fuzzy information granules-based unsupervised outlier detection method (MGBOD) is proposed in this work. In our method, granular-balls with different granularity are first generated and the fuzzy binary relations between the granular-balls with respect to different attributes are computed. Subsequently, two attribute sequences are constructed based on the importance of the attributes. Then, multi-granular-ball fuzzy binary granular structures are constructed based on these two sequences. Finally, the outlier score of the granular-ball is defined by fusing these granules in the granular structures and mapped to the samples in the granular-ball.
