Despite significant advancements made by existing works, issues such as blurred boundaries, irregular shapes, and scale variances of surface defects continue to pose substantial challenges to industrial surface defect detection tasks. We believe the more adaptive and effective representation of the complex and diverse defects is the key to addressing these challenges. To this end, this work proposes an innovative feature extractor with flexible shape imitation capability and a novel feature fuser incorporating strong semantic guidance capability. Concretely, to adaptively represent irregularly-shaped defects, we design a plug-and-play shape-imitation convolutional kernel to yield flexible receptive fields and model long-distance dependencies with a partial computation strategy and rapid feature-memory retrieval mechanism. Meanwhile, to fully characterize weak and scale-varying defects, we construct a selective semantic-guided feature pyramid structure to contextually guide the network’s attention to crucial features and dynamically cross-fuse different levels of defect features. Four lite decoupled heads with wise IoU-based losses are employed to further enhance the detector’s accuracy. Overall, this work develops an effective and efficient method that significantly improves the performance of industrial surface defect detection while maintaining a favorable accuracy-speed balance and high scene adaptability. Extensive experiments on six industrial defect datasets (steel strips, steel sheets, rails, aluminum profiles, optics, and circuit boards) demonstrate the superiority of our method over other competitive approaches. The proposed method achieves either the best or at least second-best detection accuracy with lightweight model parameters and a real-time inference speed.</div></div>","PeriodicalId":50461,"journal":{"name":"Expert Systems with Applications","volume":"279 ","pages":"Article 127334"},"PeriodicalIF":7.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769243","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}

The term “Cluster-Boosted Artificial Neural Networks” (“CBANNs”) is coined for ANNs using this technique. By adding cluster identifiers as extra input features, CBANNs enhance conventional ANNs and improve the model’s ability to identify underlying patterns in complicated data landscapes. This method offers a solution to some limitations of standard ANNs, which often struggle with high-dimensional data, local minima, and nonlinear relationships. Without the need for manual feature engineering or in-depth domain knowledge, CBANNs greatly increase prediction accuracy by employing unsupervised clustering, using k-medoids, to build a more structured input space. Various numerical results are presented which validate the superior predictive ability of CBANNs across nine benchmark functions, including De Jong’s 5th, Griewank, and Rastrigin functions. Compared to conventional ANNs with identical hyperparameters, CBANNs achieve error reductions of up to 98%, consistently demonstrating higher performance on functions with intricate geometries and multiple minima. Furthermore, CBANNs are applied to a terrain modeling problem, which proved that CBANNs can reduce the prediction error by up to 95% compared to standard ANNs, indicating their potential for high-precision applications. These findings underscore the CBANN’s ability to generalize effectively in challenging datasets, suggesting its broader applicability in fields that demand accuracy in the presence of complex data distributions.</div></div>","PeriodicalId":50461,"journal":{"name":"Expert Systems with Applications","volume":"278 ","pages":"Article 127332"},"PeriodicalIF":7.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724872","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}

Finally, five deep learning models were used to predict stock prices using feature sets with sentiment indicators.

The results show that in 10 industries, LSTM-CNN-Attention model has the best effect on stock price prediction, and after incorporating the sentiment indicator constructed by the principal component, the effect of the model is significantly improved, and the performance is the best in 7 industries.

Furthermore, we set a time threshold to partition items with interaction intervals within this threshold into a session, thereby capturing homogeneous relationships within each session. We employ the dual attention mechanism to perform local attention within each session and introduce the learned type weights of each session into the complete interaction sequence to perform global attention, thereby blurring the sequential relationships within sessions and integrating global relevance with local details to handle overly long sequences precisely.

Water temperature, being a critical water quality parameter, directly influences the growth and development of fish. Moreover, trends in water temperature can guide the timing of relay in terrestrial-marine aquaculture models. Therefore, real-time monitoring and accurate multi-step prediction of water temperature can effectively ensure the safety of fish production and avoid severe economic losses due to weather changes. However, the openness of the offshore aquaculture net pen environment makes water temperature susceptible to spatial and temporal impacts of external factors, characterized by non-linearity, dynamics, and complexity, making accurate water temperature prediction challenging. This paper proposes a Grouped Convolution Dual-Attention Network (CDANet) framework for multivariate time series prediction based on grouped dual-attention convolution, which fully considers the spatiotemporal correlation between climate conditions and water quality parameters in the pen area, the spatial distribution of water body, and the temporal dependency of historical periods in sequence data. The framework includes a global attention feature extraction module to focus on complex relationships between various factors and a local attention feature extraction module that can overcome the shortcomings of attention mechanisms and handle anomalies.
