Summary: We propose an alternative approach to the fuzzy metric concept by extending a crisp metric using a fuzzy equivalence relation. We call this extended metric an E-d metric and explore its properties and relationships with classical fuzzy metrics. Specifically, we focus on the topologies and fuzzy topologies induced by E-d metrics.

Summary: The aim of this paper is to study nonconvex optimization problems with fuzzy objective functions under the concept of granular differentiability. The paper provides the definition of granular preinvex fuzzy functions and discusses their characteristics. It proves two necessary and sufficient conditions for a granular differentiable fuzzy function to be granular preinvex. The developed theory is applied to solve a class of nonconvex fuzzy optimization problems with constraints, and the existence of the optimal solution is obtained by solving the fuzzy variational inequalities. The theory is illustrated by numerical examples.

Summary: This article investigates the consensus problem of linear multiagent systems (MASs) with uncertain dynamics and uncertain switching topology. Uncertainties are represented as granular fuzzy numbers using horizontal membership functions and relative distance measurement arithmetic. The existence of a crisp solution to a fuzzy linear matrix inequality problem is first proved, and then an algorithm is proposed for achieving consensus in the MASs with uncertainty. The efficiency of the proposed algorithm is demonstrated in a simulation example.

Summary: Formal concept analysis is an effective tool for data analysis and visualization using concept lattice. This paper introduces the tolerance threshold to the variable threshold concept lattice, forming the Robust variable threshold fuzzy Concept Lattice (RobCL). RobCL has incremental characteristics and can model the incremental cognitive process, distinguishing it from other concept lattice models. A comparative study shows that variable threshold concept lattice is a special case of RobCL.

Summary: In this paper, the relationships between ordered relations, tolerances, and formal contexts on complete lattices are studied. It is shown that the factor lattice of a complete lattice under a complete tolerance is isomorphic to the concept lattice of a context, and any ordered relation on a complete sublattice can be extended to the whole lattice. Moreover, the self-bonds of a formal context and the ordered relations on its concept lattice are proven to form isomorphic lattices.

Summary: This paper explores the relationship between Fuzzy Relation Equations (FRE) and Concept Lattices, proposing a method to reduce FRE without losing information. It considers attribute reduction theory in property-oriented and object-oriented concept lattices to detect redundant equations.

Summary: Datasets often contain imprecise data or noise, which can lead to unexpected results in mappings. One way to minimize the impact of noise on the final results is to use generalized quantifiers. This paper presents four types of generalized quantifiers based on adjoint triples, which offer a more flexible framework compared to current approaches. The properties and characteristics of these quantifiers are studied, and their application in formal concept analysis is demonstrated.

Summary: This paper introduces the concept of homomorphism on fuzzy hyperlattice ordered group (FHLOG) and studies the transformation of binary and fuzzy hyperoperations among different FHLOGs. It also defines the notion of fuzzy hypercongruence relation on FHLOG. By establishing redox reactions of copper, gold, and americium, the paper develops homomorphism and composition functions of FHLOGs. Therefore, a relation among three different metal's redox reactions, preserving binary and fuzzy hyperoperations, is established.

Summary: This article introduces a novel fuzzy alpha-neighborhood operator and a fuzzy rough set model based on this operator for decision-making in information systems. By utilizing data normalization and the fuzzy alpha-neighborhood-based fuzzy rough set model, real-valued information systems are effectively transformed into intuitionistic fuzzy-valued information systems, with three different sorting decision-making schemes developed on the latter. The method is validated through numerical experiments and comparative studies, demonstrating its stability and effectiveness.

Summary: This article examines the application of granular structures of intuitionistic fuzzy information in data mining and information processing. It defines partial-order relations at different hierarchical levels to reveal the granularity of the structures, characterizes the granularity invariance between different structures using relational mappings, and generalizes Shannon's entropies to IF entropies. The significance of intuitionistic attributes using the information measures is introduced, and an information-preserving algorithm for data reduction of IF information systems is constructed. Numerical experiments confirm the performance of the proposed technique by inducing substantial IF relations from public datasets considering the similarity/diversity between samples from the same/different classes.

Summary: This paper investigates the problem of selecting the optimal scale in numerical incomplete multi-scale information systems (NIMIS) and numerical incomplete multi-scale decision systems (NIMDS). By employing the maximal consistent block technique, the authors define the scale in NIMIS and NIMDS and propose the maximal consistent block based optimal scale. The results show that the maximal consistent block based optimal scale and the optimal scale are equivalent in consistent NIMDS, while there is no static relationship between the maximal consistent block based lower-approximation optimal scale and the upper-approximation optimal scale in inconsistent NIMDS.

Summary: This paper investigates knowledge acquisition in multi-scale information systems by deriving IF-THEN rules for multi-scale decision attributes. It introduces the concept of a generalized multi-scale decision information table (GMDIT) and defines scale selections for individual decision tables in GMDITs. The paper also describes information granules and their properties with different scale selections, formulates optimal scale selections for inconsistent GMDITs, and presents local optimal scale selections for obtaining concise decision rules. Finally, attribute reducts based on optimal scale selections are derived, and hidden decision rules in inconsistent GMDITs are unraveled.

Summary: Neural implicit representations have gained attention due to their expressive, continuous, and compact properties. However, there is still a lack of research on city-scale continual implicit dense mapping based on sparse LiDAR input. In this study, a city-scale continual neural mapping system with a panoptic representation is developed, incorporating environment-level and instance-level modeling. A tailored three-layer sampling strategy and category-specific prior are proposed to address the challenges of representing geometric information in city-scale space and achieving high fidelity mapping of instances under incomplete observation.

Summary: This paper proposes a novel unsupervised context-aware quality phrase mining framework called LMPhrase, which is built upon large pre-trained language models. The framework mines quality phrases as silver labels using a parameter-free probing technique on the pre-trained language model BERT, and formalizes the phrase tagging task as a sequence generation problem by fine-tuning on the Sequence to-Sequence pre-trained language model BART. The results of extensive experiments show that LMPhrase consistently outperforms existing competitors in two different granularity phrase mining tasks.
