However, data characterized by multi-source heterogeneity, nonlinearity, imbalance, and incompleteness pose a substantial challenge to traditional decision-making theories and methods. In view of this, this paper defines the concept of an incomplete multi-source heterogeneous attribute information system (IMHAS), introduces an attribute reduction method on IMHAS that integrates rough sets and machine learning, and combines three-way soft clustering and hybrid machine learning models. A novel theoretical framework is proposed to address uncertain decision-making problems involving data characterized by multi-source heterogeneity, nonlinearity, imbalance, and incompleteness is proposed. First, IMHAS is established and its attribute reduction method is defined using rough set, neighborhood rough set, bag-of-words, and random forest techniques. Second, to further resolve the correlation between objects in IMHAS, a three-way soft clustering method is introduced. Finally, to target decision-making for different object categories, two types of machine learning models are constructed for handling discrete and conditional decision attributes. The scientific superiority of the proposed method was verified using four distinct datasets from medical and healthcare domains. The results show that the proposed method outperforms all comparative methods, and it can effectively support uncertain decision-making in four different cases. In conclusion, this paper proposes a general theoretical framework for uncertain decision-making based on artificial intelligence techniques for incomplete multi-source heterogeneous data, thus offering realistic guidance for clinical applications involving such data.</div></div>","PeriodicalId":13842,"journal":{"name":"International Journal of Approximate Reasoning","volume":"186 ","pages":"Article 109491"},"PeriodicalIF":3.2,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on the premise that fuzzy data result from a process analogous to statistical coarsening, we introduce a conditional probabilistic approach that links observed fuzzy statistics (e.g., mode, spread) to the underlying, unobserved statistical model, which depends on external covariates. The inferential problem is addressed using Approximate Bayesian methods, mainly through a Gibbs sampler incorporating a quadratic approximation of the posterior distribution. Simulation studies and applications involving external validations are employed to evaluate the effectiveness of the proposed approach for fuzzy data analysis.

However, current conflict analysis weighting models face significant limitations when dealing with incomplete data and dispersed knowledge. Objective methods are sensitive to missing values and struggle to accurately capture authentic preferences, while subjective approaches lack systematic evaluation criteria, leading to substantial randomness in weight assignments. Therefore, a three-way conflict analysis model via the best-worst method is proposed, which is combined with a correlation coefficient method to balance subjective preferences and objective data. First, the trisection of agent pairs is derived through Bayesian minimum risk. Subsequently, a new conflict distance function is defined on the incomplete information system to provide a more precise measurement of conflict degrees. Then, for incomplete and dispersed information systems, a maximal coalition-based agent partitioning algorithm is designed, along with a new weighted voting mechanism to aggregate dispersed knowledge. Finally, the scientific transparency of the weighting process, as well as the robustness and feasibility of the model, are demonstrated through experimental analysis.</div></div>","PeriodicalId":13842,"journal":{"name":"International Journal of Approximate Reasoning","volume":"186 ","pages":"Article 109490"},"PeriodicalIF":3.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 answer requires extending natural revision from simple formulae expressing universal truths (something holds) to conditionals expressing conditional truth (something holds in certain conditions). The extension is based on the basic principles natural revision follows, identified as minimal change and naivety: change mind as little as possible; believe what not contradicted.

However, existing analysis methods focus primarily on scalar data and give little attention to addressing the challenges posed by nonscalar data, e.g., functional data, which are prevalent in many real-world applications. Additionally, most methods assume a static graphical model within the observed period, neglecting the dynamic changes that may occur over time. In this paper, we propose a novel method for predicting graphical models based on functional data. Our approach transforms functional data into finite-dimensional vectors via basis function expansion and cross-validation. We then establish a sequential prediction model for determining the correlation coefficient matrix of the decomposed data, thus accounting for the constraints imposed on the matrix via a transformation technique. Finally, we employ conditional independence tests to identify the edges of the predicted graphical model. We demonstrate the effectiveness of our method through extensive simulations and real data analyses. The results show that our method performs better than the competing methods in terms of prediction accuracy and provides valuable insights into the dynamic changes exhibited by a network. This work opens new possibilities for conducting graphical model analyses in various domains, particularly in terms of handling functional data and predicting dynamic relationships.</div></div>","PeriodicalId":13842,"journal":{"name":"International Journal of Approximate Reasoning","volume":"186 ","pages":"Article 109493"},"PeriodicalIF":3.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we address the question of how to quantify uncertainty in ordinal classification, where class labels have a natural (linear) order. We reckon that commonly used uncertainty measures such as Shannon entropy, confidence, or margin are not appropriate for the ordinal case. In our search for better measures, we draw inspiration from the social sciences literature, which offers various measures to assess so-called consensus or agreement in ordinal data. We argue that these measures, or, more specifically, the dual measures of dispersion or polarization, do have properties that qualify them as measures of uncertainty. Furthermore, inspired by binary decomposition techniques for multi-class classification in machine learning, we propose a new method that allows for turning any uncertainty measure into an ordinal uncertainty measure in a generic way. We evaluate all measures in an empirical study on twenty-three ordinal benchmark datasets, as well as in a real-world case study on automotive goodwill claim assessment.
