Traditional static strategies struggle to keep up with the rapidly shifting market sentiment and herd behavior, leading to delayed decision-making and risk management failures. To enhance investment efficiency and improve risk control, we propose a dynamic multi-criteria nested sequential three-state three-way decision (TS3WD) model based on herd behavior to identify and implement herd behaviors and optimize the futures portfolio strategy. Firstly, this paper proposes a method for determining optimistic and pessimistic conditional probabilities based on loss functions, deriving new TS3WD and simplified decision rules. Secondly, the herd behavior discrimination method is introduced to divide it into positive, neutral, and negative herd behaviors for holding futures contracts. Thirdly, four minimum adjustment optimization models for positive and negative herd behaviors under optimistic and pessimistic attitudes are constructed based on new decision rules, respectively, and a method based on the self-confidence principle for neutral herd behavior is presented, providing a quantitative model for implementing herd behaviors. Subsequently, a progressive dynamic algorithm based on a multi-criteria nested sequential TS3WD model is proposed to deduce the futures portfolio strategy, which dynamically identifies and adjusts loss functions to obtain the optimal futures investment behavior, forming a complete futures portfolio strategy. Finally, we apply the proposed method to solve the metal futures portfolio strategy in the Shanghai Futures Exchange, providing implications for investors in the futures market through sensitivity and comparative analyses.</div></div>","PeriodicalId":51063,"journal":{"name":"Information Sciences","volume":"708 ","pages":"Article 122043"},"PeriodicalIF":8.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549448","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}

Class activation mapping (CAM) provides visual explanations and object localization for convolutional neural networks (CNNs) by highlighting regions of interest corresponding to specific classes. However, existing approaches tend to focus solely on discriminative regions and often contain excessive noise. In this paper, we propose a simpler and more efficient method called PCG-CAM, which provides visual explanations for brain tumor diagnosis and generates fine-grained pseudo-labels. PCG-CAM extracts the principal components of gradients and uses their absolute values as weights for the feature maps, thereby better reflecting the importance of each feature map while preserving more object features. We evaluated the saliency maps generated by PCG-CAM on weakly-supervised brain tumor segmentation and assessed their generalizability in object localization tasks. Specifically, our method achieves 47.42% mIoU in weakly-supervised brain tumor segmentation, outperforming other methods by nearly 10% on average. The results on brain MRI and natural images demonstrate that our method effectively localizes target positions and provides robust explanations for model decisions.</div></div>","PeriodicalId":51063,"journal":{"name":"Information Sciences","volume":"708 ","pages":"Article 122046"},"PeriodicalIF":8.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579088","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}

Conventional offline-trained deep learning models often fail to provide accurate predictions for such semi-supervised data streams. Therefore, a quality-relevant deep rule-based system with complementary lifelong learning (QDRSCLL) is proposed to enable adaptive prediction of critical quality variables in streaming data environments. QDRSCLL comprises a deep backbone network and a shallow predictor. The former utilizes a semi-supervised quality-relevant stacked autoencoder (SQSAE) for feature extraction, while the latter employs a hierarchical fuzzy rule system (HFRS) to perform fuzzy inference on hierarchical hidden features. Furthermore, a novel complementary lifelong learning mechanism is proposed to enable QDRSCLL with online incremental learning capabilities. Additionally, semi-supervised learning is integrated into the online learning process to further enhance its deep feature extraction capabilities and the prediction performance. The feasibility and superiority of the proposed method are demonstrated through two real-world processes and four synthetic datasets.

To address those, there is a need for approaches less affected by missing edges and easy to obtain communities.

First, by edge augmentation, the network with missing edges is integrated into complete networks. Second, the <em>k</em>-core algorithm is used to obtain core node information and build a similarity matrix, followed by an unsupervised deep method that implements network embedding to obtain a low-dimensional feature matrix.

By mapping the problem to a heterogeneous graph with distinct node and edge types, an end-to-end learning model is developed. The model integrates a heterogeneous graph neural network (HGNN) and sequential Q networks to effectively represent the key scheduling elements and the Markov decision-making process. HGNN is employed to extract meaningful features and representations from the heterogeneous graph. These representations are then fed into the sequential Q networks to select two cooperated actions to be taken.

In the vast majority, the fault diagnoser is constructed based on the complete system model, which may have a huge number of states, due to the parallel composition of several modules. The implementation of diagnosers with a large number of states consumes a large amount of computer memory, and may become, in some cases, unfeasible. Recently, synchronous diagnosis of DES has been proposed, where state observers of fault-free models of system modules are used for fault diagnosis. The method provides a diagnoser that is not based on the composed plant model, which leads to a diagnoser with fewer states and transitions than the classical diagnoser. In the synchronous diagnosis approach, all the subsystem models are assumed to contribute to fault detection. However, in practice, certain subsystems may not provide useful information on fault occurrences, or redundant information may be available from other modules. Consequently, these redundant modules are not necessary in the synchronous diagnosis scheme and can be discarded, leading to reduced diagnosers. In this paper, we present a method for computing a synchronous diagnoser that uses only part of the subsystem models. It is also shown that the fault can be diagnosed using modules where the fault event is not even modeled. To do so, we present an algorithm for computing all the sets of modules that ensure the synchronous diagnosability of a DES. These sets are called synchronous diagnosis bases (SDB). We prove that the complexity of the problem of finding an SDB with cardinality less than or equal to a given natural number is NP-complete. Thus, the algorithm proposed in this work has the objective of mitigating the computational efforts to find all the SDB of a DES.

Although they generalize well, their learning with queries is limited since they guide learning with the average query which merges all queries without considering that queries in TKG represent diverse meanings. Merging diverse queries generates a vague averaged query which will mislead embedding learning and further confuse predictions. To resolve the limitation, we propose individual-query-guided learning (IndiQ) to learn clearer embeddings which faithfully realizes the nature of TKG that its records are diverse and should be modeled individually rather than averaging. Specifically, IndiQ formulates embedding learning as a weighted sum of entity-related facts and calculates weights using queries individually following the total probability theorem. Then, with the novel formulation, IndiQ guides the learning of entity embeddings using queries individually to identify important facts. Finally, IndiQ predicts future links using learned entity embeddings. Experimental results show that we achieve better performance.
