A hypergraph is a type of graph, H=(V,E) where V is the set of nodes and E is the set of hyperedges;where one edge consists of may nodes. Morphological operators are nonlinear operators which can be applied on images, graphs, hypergraphs etc. Dilation and erosion are morphological operators and other operators like opening, closing can be obtained by repeated application of these operators. Topological space consists of a set X together with topology τ defined on X, which satisfies the axioms namely Nullset, arbitrary union of opensets and finite intersection of opensets. Such a topological space S=(X,T) is compatible with a hypergraph H if X=VH∪EH where VH and EH are the vertex set and edge set respectively. The morphological operators induces several topology on hypergraph with its compatible topological space S=(X,T). Neighborhood of a node is defined in many ways which can be considered as open sets in the corresponding topological space. The purpose of this paper is to apply topological properties on hypergraphs using morphological operators. Separation axiom and closure function are illustrated using hypergraph structure. The work is extended to crime analysis, text processing and patient disease analysis. Topological feature extraction is done on Barcodes created from crime hypergraphs. This gives a better visualization of crime analysis. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In the realm of consumer electronics, the integration of knowledge graphs with causal inference significantly advances recommendation systems within the Artificial Intelligence of Things (AIoT). This paper introduces a novel method that addresses the limitations of traditional AIoT-based systems, which tend to prioritize correlation over causality and demonstrate limitations in navigating inference paths across knowledge graphs. A reinforcement learning based knowledge graph model is designed to enhance interpretability and trustworthiness in recommendation processes. A soft reward strategy is employed within a Markov decision process, utilizing a multi-hop scoring function to ensure rational outcome assessments. Additionally, a graph search algorithm with user-conditional action pruning is incorporated to facilitate efficient and accurate sampling of inference paths. Experimental results indicate significant improvements in key performance metrics such as normalized discounted cumulative gain, recall, hit ratio, and precision ratio over existing methods. Furthermore, interpretable reasoning paths are provided, establishing a new benchmark in the AIoT-driven recommendation landscape for consumer electronics. © 1975-2011 IEEE.

This qualitative research paper explores how internship experiences impact the recognition component of engineering professional identity for first-generation, low-income (FGLI) engineering students, drawing on the performance/competence, interest, and recognition (PCIR) framework. Technical experiences in internships are a crucial component of engineering internships, as they develop technical skill sets in real-world settings. However, the role of technical experiences in internships in developing recognition for FGLI students has not yet been explored. Ten FGLI students at a mid-size, private, highly-selective university in the United States participated in semi-structured interviews conducted through video-conferencing, of which six were selected for this paper due to their in-depth discussions on technical internships. After transcription, interview data were coded and analyzed using cluster matrix techniques that specifically targeted recognition-related codes. We found that participants who were assigned and supported in technical work felt recognized as an engineer by their colleagues and managers. The opposite was true when they were not assigned or supported in technical work. This work showcases that internships represent a highly contested locale in which recognition becomes the currency through which engineering professional identity could be cultivated or inhibited in FGLI students. © American Society for engineering Education, 2022.

We propose that a tree-like hierarchical structure represents a simple and effective way to model the emergent behaviour of financial markets, especially markets where there exists a pronounced intersection between social media influences and investor behaviour. To explore this hypothesis, we introduce an agent-based model of financial markets, where trading agents are embedded in a hierarchical network of communities, and communities influence the strategies and opinions of traders. Empirical analysis of the model shows that its behaviour conforms to several stylized facts observed in real financial markets;and the model is able to realistically simulate the effects that social media-driven phenomena, such as echo chambers and pump-and-dump schemes, have on financial markets. © 2024 The Authors.

In previous studies on facial video depression recognition, although convolutional neural network (CNN) has become a mainstream method, its performance still has room for improvement due to the insufficient extraction of global and local information and the neglect of the correlation of temporal and spatial information. This paper proposes a novel dual-task enhanced global–local temporal–spatial network (DTE-GLTS) to enhance the extraction capability of global and local features and deepen the analysis of temporal–spatial information correlation. We design a dual-task learning mode that utilizes the data-efficient image transformer (Deit) as the main body to learn the global features of video sequences and guides Deit to learn local features with the pre-trained temporal–spatial fusion network (TSF). In addition, we propose the TSF mechanism to more effectively fuse temporal–spatial information in video sequences, strengthen the correlation between frames and pixels, and embed it in Resnet to form the TSF network. To the best of our knowledge, this is the first application of Deit and dual-task learning mode in the field of facial video depression recognition. The experimental results on AVEC 2013 and AVEC 2014 show that our method achieves competitive performance, with mean absolute error/root mean square error (MAE/RMSE) scores of 6.06/7.73 and 5.91/7.68, respectively, while significantly reducing the number of parameters. © 2024 John Wiley & Sons Ltd.

Time series forecasting, while vital in various applications, often employs complex models that are difficult for humans to understand. Effective explainable AI techniques are crucial to bridging the gap between model predictions and user understanding. This paper presents a framework - TSFeatLIME, extending TSLIME, tailored specifically for explaining univariate time series forecasting. TSFeatLIME integrates an auxiliary feature into the surrogate model and considers the pairwise Euclidean distances between the queried time series and the generated samples to improve the fidelity of the surrogate models. However, the usefulness of such explanations for human beings remains an open question. We address this by conducting a user study with 160 participants through two interactive interfaces, aiming to measure how individuals from different backgrounds can simulate or predict model output changes in the treatment group and control group. Our results show that the surrogate model under the TSFeatLIME framework is able to better simulate the behaviour of the black-box considering distance, without sacrificing accuracy. In addition, the user study suggests that the explanations were significantly more effective for participants without a computer science background. © 2024 IEEE.

To ensure the security of image information and facilitate efficient management in the cloud, the utilization of reversible data hiding in encrypted images (RDHEI) has emerged as pivotal. However, most existing RDHEI schemes suffer from lower security and limited embedding capacity. To tackle these challenges, we propose a reversible data hiding with secret encrypted image sharing and adaptive coding scheme. Specifically, in the encryption phase, we introduce an improved secret sharing (SS) encryption method based on the chinese remainder theorem for polynomials (CRTP). This method not only improves the security of encrypted images but also vacates a larger room for embedding. In the embedding phase, we introduce an adaptive coding embedding approach using XOR preservation (XORP) and huffman coding, which provides high embedding capacity. Experimental results and security analysis demonstrate that our proposed encryption method achieves optimal values in security indicators for encrypted images, such as information entropy, histograms, NPCR and UACI. The proposed embedding method is superior to some state-of-the-art schemes in terms of embedding capacity. Furthermore, in datasets BOSSBase and BOWS2, the average embedding rates of the proposed embedding approach can reach 2.1745 bpp and 2.0656 bpp, respectively. © 2025 IEEE.
