Due to the similarity of the fault categories to be classified between different models, an unauthorized user may easily transfer a diagnosis model to his own domain, infringing the interests of the model owner. Therefore, it is important to protect the intellectual property of fault diagnosis models. The existing privacy protection methods use a metric to increase the feature divergence or construct un-transferable isolation domains, but the generalization boundaries of the deep learning models cannot be minimized enough, leading to certain availability in unauthorized domains. To tackle this issue, a style relationship preserving based model property protection method is proposed for fault diagnosis in this paper. The proposed method utilizes style transfer technique to simulate the extreme situation, which further compacts the generalization areas and limits the application of the model to unauthorized domains. Comprehensive experiments are established on a public fault diagnosis dataset and a practical rolling bearing fault diagnosis test platform, demonstrating the effectiveness and superiority of the proposed method in model privacy protection.</div></div>","PeriodicalId":50461,"journal":{"name":"Expert Systems with Applications","volume":"272 ","pages":"Article 126730"},"PeriodicalIF":7.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360217","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 designed BSIA-Net consists of three parts including semantic flow, boundary flow, and aggregation flow. The semantic flow is used to extract multi-scale semantic information and constructs astrous stack pooling (ASP) module to capture rich context information by expanding the receptive field. The boundary flow is specifically designed to refine low-level boundary feature from edge extracting operator (EEO) by multi-scale semantic features. The aggregation flow constructs interactive aggregation module (IAM) to capture long-range dependencies between the inner objects and boundaries by interactively enhancing intra-class consistency.

To address these challenges, this paper introduces an innovative interpretable ensemble tree method, EnEXP. This method generates a sample set by applying fixed masking perturbation to individual samples, then constructs multiple decision trees using bagging and boosting techniques and interprets them based on the importance outputs of these trees, thereby achieving a global interpretation of the entire dataset through the aggregation of all sample insights.

However, static KGs fail to capture continuously emerging entities and relations over time. Temporal knowledge graphs address this by incorporating time information or providing multiple sequential snapshots of a static knowledge graph. Most existing work focuses on static KGs with fixed sets of entities and relations, meaning existing methods still struggle to encode emerging entities and relations. Therefore, we propose a novel methodology of combining language models and graph structure to enable the encoding of unseen entities and relations for temporal KG completion. Specifically, we encode relations with RoBERTa and entities using neighbouring relations alongside the entity’s relation type to provide contextual information. We evaluate our methodology on three datasets with emerging entities and relations over temporal snapshots: LKGE-Hybrid, FB-MBE, and the mergers and acquisitions domain TKGQA dataset. Our experiments show that our model achieves new state-of-the-art results on FB-MBE and LKGE-Hybrid while providing strong benchmark results for the TKGQA dataset. Our ablation studies show us that graph structure information is only beneficial if there is sufficient connectivity with the knowledge graph since sparser knowledge graphs can lead to noisy signals. We also explore the performance of Llama v2 on temporal link prediction, and the results show that current LLMs struggle with domain-specific temporal link prediction. Overall, our work provides an essential advance around effectively encoding continuously emerging entities and relations for temporal link prediction across evolving knowledge graphs over time.</div></div>","PeriodicalId":50461,"journal":{"name":"Expert Systems with Applications","volume":"272 ","pages":"Article 126648"},"PeriodicalIF":7.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143377203","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}
