Summary: This study improves the Variable Precision Multigranulation Fuzzy Rough Sets (VP-MFRSs) by proposing Decision-Theoretic Multigranulation Fuzzy Rough Sets (DT-MFRSs) which systematically fuse the multigranulation maximum and minimum. DT-MFRSs provide tri-level analysis of measurement, modeling, and reduction via three-way decisions. The study extends and improves VP-MFRSs by introducing optimistic, pessimistic, and compromised models, and enhances uncertainty optimization through a new reduction criteria.

Summary: The work proposes a new method to detect influential news in online communities by applying the Three-Way Decisions approach based on Probabilistic Rough Sets to categorize online users into three parts. It then maps these parts onto a structure called Hexagons of Opposition to reason about the impact of news on opinions of specific communities over time, introducing two indicators to measure the impact of news. The method has been experimented on real data and discussed with promising results.

Summary: In this paper, we propose a method to transform linguistic set-values into numerical values based on granular structures for multi-scale decision tables. We construct a relatively objective and comprehensive total cost for optimal scale selection, including test cost, delay cost, and misclassification cost. An OSS algorithm is designed based on the order of uncertainty and total cost. The feasibility and effectiveness of the algorithm are verified through experiments on UCI data sets.

Summary: In this paper, we extended the concepts of three-way decisions (3WD) and decision theoretic rough sets (DTRS) in the framework of Complex q-rung orthopair 2-tuple linguistic variables (CQRO2-TLV) and discussed their important properties. We also introduced the CQRO2-TL GMSM (CQRO2-TLGMSM) operator and the weighted CQRO2-TL GMSM (WCQRO2-TLGMSM) operator, and demonstrated their properties such as idempotency, commutativity, monotonicity and boundedness. Furthermore, we investigated a CQRO2-TL DTRS model and conducted a comparative study to validate the authenticity, supremacy, and effectiveness of our proposed notions.

Summary: Variable precision (fuzzy) rough sets are generalizations of Pawlak rough sets that handle uncertain and imprecise information well. However, many existing variable precision (fuzzy) rough sets lack the comparable property (CP), which is fundamental in Pawlak rough sets. To address this issue, a novel variable precision fuzzy rough set model with CP is proposed, along with an associated three-way decision model.

Summary: This study proposes a hybrid method that involves Weighted Sum and Artificial Bee Colony Algorithm to optimize thresholds. The method conducts multi-objective optimization of uncertainty, impurity, and correlation and generates optimal (alpha, beta) pairs for data trisecting. The results show that the proposed method outperforms in terms of optimal qualities, multiple optimum thresholds, minimal size of boundary regions, and better evaluation results compared to Information-theoretic rough sets and Game-theoretic rough sets.

Summary: This paper generalizes the model of three-way decision from 0-1 tables to general information tables, with the assignment of values to the set of objects and the construction of tri-partitions. The fundamental result identifies finitely many pairs of thresholds and describes the variation of the positive region based on thresholds. The evaluation of these finite tri-partitions by weighted entropy allows for obtaining an optimal tri-partition.

Summary: The recent advancements in IoT have brought significant advantages for businesses, but the protection of data privacy has become an important research challenge. Differential privacy, a new technique, anonymizes sensitive attributes to protect data privacy. A key issue in existing studies is the costly manual division of attribute sets by domain experts. This paper introduces a three-way approach for differential privacy and an algorithm for attribute set division, demonstrating considerable improvement in information content and dataset stability.

Summary: In this work, a two-stage denoising framework (TSDF) is proposed for zero-shot learning (ZSL) to address the issue of noisy labels. The framework includes a tailored loss function to remove suspected noisy-label instances and a ramp-style loss function to reduce the negative impact of remaining noisy labels. In addition, a dynamic screening strategy (DSS) is developed to efficiently handle the nonconvexity of the ramp-style loss.

Summary: This paper proposes an enhanced scatter search strategy, using opposition-based learning, to solve the problem of automated test case generation based on path coverage (ATCG-PC). The proposed ESSENT algorithm selects the path with the lowest path entropy among the uncovered paths as the target path and generates new test cases to cover the target path by modifying the dimensions of existing test cases. Experimental results show that the ESSENT algorithm outperforms other state-of-the-art algorithms, achieving maximum path coverage with fewer test cases.

Summary: Linking digital accounts belonging to the same user is crucial for security, user satisfaction, and next-generation service development. However, research on account linkage is mainly focused on social networks, and there is a lack of studies in other domains. To address this, we propose SmartSSO, a framework that automates the account linkage process by analyzing user routines and behavior during login processes. Our experiments on a large dataset show that SmartSSO achieves over 98% accuracy in hit-precision.
