Existing methods that rely on a single metric often fail to capture the full complexity of such networks. To address these limitations, we propose a novel ranking aggregation-based algorithm for spatial network disintegration. Our approach integrates multiple region centrality metrics, providing a comprehensive evaluation of region importance. The algorithm operates in two stages: first, multiple rankings based on different centrality metrics are aggregated into a composite ranking to refine the candidate regions for disintegration. In the second stage, an exact target enumeration method is applied within this candidate set to determine the optimal combination of regions that maximizes disintegration impact. This interconnected approach effectively combines ranking aggregation with targeted enumeration to ensure both efficiency and accuracy. Extensive experiments are conducted on synthetic and real-world spatial networks of different network configurations. The results demonstrate that our method consistently achieves superior disintegration performance compared to traditional approaches, effectively addressing the challenges associated with spatial network disintegration.

With a special emphasis on COVID-19, the present work focuses on the Omicron variant, recognizing its significance in the global context of infectious diseases. The proposed research evaluates the effectiveness of both univariate and multivariate frameworks utilizing statistical and deep learning approaches to forecast the spread of the epidemic. Forecasting robustness is boosted by effectively correlating linear and non-linear components with the original series. To improve the performance, correlation is facilitated using correlation-driven weights within the statistically enforced deep learning model (WD-ensemble framework). The modeling process utilizes 493 data points and multivariate time-series records, including infected cases, vaccinated cases, and stringency index. The training dataset spans from November 1, 2021, to January 17, 2023, while the testing dataset covers the period from January 18, 2023, to March 8, 2023. The proposed WD-ensemble framework, incorporating stochasticity, outperforms all other state-of-the-art models, yielding highly reliable forecasts with remarkably low RMSE of 907.54, MAPE of 0.0008, and MAE of 670.78. It demonstrates a reduction in error percentages compared to the top-performing existing model, with decreases of 30.0267% in RMSE, 20% in MAPE, and 24.9411% in MAE. A pivotal revelation in this research is the robust negative correlation (-0.86) between vaccinated and confirmed cases as compared to the stringency index, implying that widespread vaccination could warrant the relaxation of stringent measures, including business and school closures.</div></div>","PeriodicalId":50365,"journal":{"name":"Information Processing & Management","volume":"62 1","pages":"Article 103954"},"PeriodicalIF":7.4,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To bridge this gap, we propose a three-stage Retrieve–Revise–Refine framework which explicitly addresses the need for conciseness by utilizing both small and large language models (LMs) in distinct yet complementary roles. Empirical evaluations on the COLIEE 2022 and 2023 datasets demonstrate that our framework significantly enhances performance, achieving absolute increases in the macro F2 score by 3.17% and 4.24% over previous state-of-the-art methods, respectively. Specifically, our Retrieve stage, employing various tailored fine-tuning strategies for small LMs, achieved a recall rate exceeding 0.90 in the top-5 results alone—ensuring comprehensive coverage of entailing articles. In the subsequent Revise stage, large LMs narrow this set, improving precision while sacrificing minimal coverage. The Refine stage further enhances precision by leveraging specialized insights from small LMs, resulting in a relative improvement of up to 19.15% in the number of concise article sets retrieved compared to previous methods.

Finally, the glyph knowledge is fused with the pre-trained model representations to obtain semantically richer representations.

The former relies on shadow data and models, which are difficult to obtain in practical applications, while the latter depends solely on perturbation distance, resulting in insufficient identification performance. To this end, we propose a Spatial Projection-based Relative Information Loss (SPRIL) MIA to ascertain the sample membership by flexibly controlling the size of perturbations in the noise space and integrating relative information loss. Firstly, we analyze the alterations in predicted probability distributions induced by adversarial perturbations and leverage these changes as pivotal features for membership identification. Secondly, we introduce a spatial projection technique that flexibly modulates the perturbation amplitude to accentuate the difference in probability distributions between member and non-member data. Thirdly, this quantifies the distribution difference by calculating relative information loss based on KL divergence to identify membership. SPRIL provides a solid method to assess the potential risks of DNN models in MLaaS and demonstrates its efficacy and precision in black-box and white-box settings.
