Bugs cause problems ranging from stability to operability and are typically the result of human error during the programming process. They could be the result of a mistake or error, as well as a fault or defect. Software bugs should be discovered during the testing stage of the software development life cycle, but some may go undetected until after deployment. When addressing a bug, it is critical to consider its priority, which is determined manually. However, it was a difficult task, and making the wrong decision could lead to major software failures. Therefore, the primary goal of this study is to propose an ensemble approach for predicting bug priority levels in bug reports. We make use of Bugzilla's dataset, which includes over 25,000 bug reports. After preprocessing the data, this study applies a variety of feature extraction techniques, including Glove, Word2Vec TF-IDF, and Doc2Vec. Then, a model that primarily employs seven architectures of Convolutional Neural Network (CNN) Algorithms, including AlexNet, LeNet, VGGNet, 1DCNN, ResNet, ZF Net, and DenseNet as the basic models. The five architectures with the highest accuracy were then used in the ensemble method, which included ResNet, DenseNet, LeNet, AlexNet, and 1DCNN, with the final results determined by the majority values. The ensemble approach performed with 79.18 % of the final accuracy result. Other architectures include AlexNet 77.1 %, ZF Net 44.50 %, VGG Net 39.30 %, 1DCNN 75.44 %, ResNet 77.34 %, DenseNet 77.32 %, and LeNet 48.58 %. It was discovered that the proposed ensemble model outperformed each algorithm. Finally, when a new bug is discovered, it can be added to the proposed model, which will then determine its priority level.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"175 ","pages":"Article 113098"},"PeriodicalIF":7.2,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735024","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}

Compared to single-view analysis, this integration of information leads to more accurate and comprehensive clustering results, providing a solution for large-scale data clustering. Notably, various techniques have been proposed in the field. In the present context, most multi-view clustering methods mainly focus on enhancing the consistency of clustering and handling noise. Adapting multi-view subspace clustering effectively for the clustering of big data poses a significant challenge. To overcome this challenge, we propose a new method called “robust and fast subspace representation learning for multi-view subspace clustering (RFSR)”, which utilizes a unified encoder to process information from each view and integrates the information between different views. In this process, we reduce the impact of noise, employing either correntropy or <span><math><msub><mrow><mi>ℓ</mi></mrow><mrow><mi>2,1</mi></mrow></msub></math></span>-norm for handling it. Specifically, we start by randomly sampling from each view and then process the sampled data for noise. Subsequently, we train a unified encoder for each view to leverage complementary information from multiple views, thereby enhancing the robustness of clustering.

Traditional recommendation models often lack sufficient interpretability and fail to effectively leverage the interactive data generated during curriculum learning or account for the impact of individual learning styles on recommendations. To address these limitations, this study proposes a novel model, Course Recommendations based on Graph Convolutional Networks and Learning Styles to Optimize Learning Paths. Firstly, learner-course interaction data is recursively propagated through graph convolutional networks to generate predictive scores for courses. Secondly, a matching scale between courses and learning styles is established to compute similarity scores. Finally, the predictive scores and learning style similarity scores are integrated to achieve personalized course recommendations.

To address these issues, this study proposes an adaptive sampling-based ensemble federated learning framework.
