To address these issues, we propose tasks-embedded reparameterization (TER), a novel parameter-efficient fine-tuning framework that exploits multitask learning to enhance task-specific capabilities.

Furthermore, it employs a dynamic, task-oriented gating mechanism to optimize the prompts output by the model. This method dynamically adjusts the parameters according to the differing requirements of the task, ensuring that the model optimally adjusts the parameters according to the specific requirements of the task, so that the task can find a suitable balance between different tasks and improve knowledge sharing and task adaptability.

Yet, the challenges of high dimensionality and noisy financial data often undermine the effectiveness of existing financial fraud detection systems. To address these issues, this study proposes SISAE-METADES, a novel framework that integrates a supervised input-enhanced stacked autoencoder (SISAE) with a meta-learning–based dynamic ensemble selection (METADES) strategy. Unlike conventional stacked autoencoders, SISAE concatenates the original input at each encoding stage and incorporates label supervision, thereby learning task-relevant and class-discriminative representations. These enriched deep features improve both the diversity and competence of base classifiers and enable METADES to achieve more reliable local competence estimation. We validate the proposed framework using financial statement data from Chinese A-share listed companies (2005–2023), covering 71 indicators. Experimental results show that SISAE-METADES significantly outperforms standalone SISAE, traditional METADES, and several state-of-the-art baselines. In particular, it achieves substantial improvements in accuracy, recall, and F1-score, underscoring the robustness and effectiveness of combining supervised deep representation learning with dynamic ensemble selection for financial fraud detection.

However, it poses unique challenges due to the complexity and subjective nature of the visual information. This can be attributed to the significant presence of semantically ambiguous images within the current benchmark datasets, which enhances the performance of sentiment analysis but ignores the differences between various annotators. Moreover, most current methods concentrate on improving local emotional representations that focus on object extraction procedures rather than utilizing robust features that can effectively indicate the relevance of objects within an image through color information. Motivated by these observations, this paper addresses the need for efficient algorithms for labeling and classifying sentiment from visual images by introducing a novel hybrid model, which combines content-based image retrieval (CBIR) and a multi-input convolutional neural network (CNN). The CBIR model extracts color features from all dataset images, creating a numerical representation for each. It compares a query image to dataset images’ features to find similar features. This process continues until the images are grouped according to color similarity, which allows accurate sentimental categories based on similar features and feelings. Then, a multi-input CNN model is utilized to extract and efficiently incorporate high-level contextual visual information. This model comprises 70 layers, with six branches, each containing 11 layers. It seeks to facilitate the fusion of complementary information by incorporating multiple input categories that differ according to the color features extracted by the CBIR technique. This feature enables the model to understand the target and generate more precise predictions fully. The proposed model demonstrates significant improvements over existing algorithms, as evidenced by evaluations of six benchmark datasets of varying sizes. Also, it outperforms the state of the art in sentiment classification accuracy, getting 87.88%, 84.62%, 84.1%, 83.7%, 80.7%, and 91.2% accuracy for the EmotionROI, ArtPhoto, Twitter I, Twitter II, Abstract, and FI datasets, respectively. Furthermore, the model is evaluated on two newly collected large datasets, which confirm its scalability and robustness in handling large-scale sentiment classification tasks, and thus achieves a significant accuracy of 85.21% and 83.72% with the BGETTY and Twitter datasets, respectively. This paper contributes to the advancement of visual sentiment classification by offering a comprehensive solution for analyzing sentiment from images and laying the foundation for further research.</p>","PeriodicalId":14089,"journal":{"name":"International Journal of Intelligent Systems","volume":"2025 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/int/5581601","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145317290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this, self-organizing maps (SOM) clustering is utilized to segment the samples into five distinct risk levels. For the second step, we utilized triangulated maximally filtered graph (TMFG) and maximally filtered clique forest (MFCF) to minimize the number of indicators based on the dependent relationships between variables. These are then combined with Gaussian Markov random field (GMRF) and Copula algorithms to address nonlinear situations, forming what we refer to as the LoGo model. To further enhance the accuracy of LoGo models, we utilize the square Mahalanobis distance to compute the log-likelihoods as part matrix. The results reveal that the enhanced LoGo model with part matrix improves average accuracy by 7% compared with the original models without part matrix, albeit with a tenfold increase in execution time. MFCF demonstrates superior performance over TMFG in linear situations, achieving a 40% higher accuracy. However, under nonlinear circumstances, TMFG only requires half the execution time of MFCF, yet achieves a slightly higher average accuracy.

Compared to other optimization algorithms, SMA has fewer parameters, faster convergence speed, and stronger optimization capabilities. However, the standard SMA uses two randomly selected individuals to guide the search direction of the population, which results in excessive randomness during the search process. This can lead to the loss of valuable information and waste computational resources. To overcome these limitations, this study proposes an enhanced slime mold algorithm (S2SMA) based on a spiral sensing search mechanism. The main contributions of this study are as follows: Firstly, a fitness–distance balanced oscillation search mechanism is introduced to solve the issue of lack of guidance in the individual oscillatory search phase in the original SMA, thus enhancing the global exploration ability of the algorithm. Secondly, the spiral sensing search mechanism is introduced, reshaping the random redistribution behavior in SMA. This aims to fully utilize the effective information in the existing population, improve search efficiency, and enhance population diversity. Finally, the computational logic of SMA is restructured based on the existing parameters, improving the algorithm’s performance while avoiding additional computational overhead. To validate the effectiveness of the proposed S2SMA, experiments were conducted on 71 test instances from the IEEE CEC2017 and IEEE CEC2021 benchmark sets, as well as three engineering problems.

We propose a novel deep learning model, VAN-ConvLSTM, for rapid and accurate prediction of UAV downwash airflow. Unlike conventional ConvLSTM-based frameworks, which struggle with modeling long-range dependencies and detailed spatial variations, our model introduces a visual attention unit (VAN) to enhance spatiotemporal sensitivity. The model architecture combines a convolutional encoder for spatial feature extraction, a VAN module for attention-guided temporal modeling, and a ConvLSTM decoder for sequence generation. This synergistic design improves both the accuracy and interpretability of airflow prediction. Experimental results show that the VAN-ConvLSTM model achieves an SSIM score of 0.96, demonstrating high consistency with CFD simulations. Compared to baseline methods, our model reduces error while improving stability and spatial fidelity. Ablation studies further validate the individual contributions of VAN and ConvLSTM modules.
