Multi-View Polymer Representations for the Open Polymer Prediction

Recent advancements in Human-Object Interaction (HOI) detection have seen the rise of Transformer-based methods. However, these methods do not adequately model the relational structures essential for recognizing interactions. This paper introduces Multimodal Graph Network Modeling (MGNM), which utilizes Graph Neural Networks (GNNs) to better capture the relationships between human-object pairs, thereby enhancing HOI detection through a four-stage graph structure and a multi-level feature interaction mechanism.

Graph neural networks (GNNs) are essential for analyzing relational data, categorized into convolutional, attentional, and message-passing variants. The standard message-passing approach, while expressive, overlooks the rich contextual information from the broader local neighborhood, limiting its ability to learn complex relationships. This article introduces a new framework called neighborhood-contextualized message-passing (NCMP) to address this limitation, enhancing the expressivity and efficiency of GNNs.

Graph Neural Networks (GNNs) are crucial for analyzing graph-structured data, but current models overlook the conservation laws relevant to physical resource flows, such as electrical currents in power grids. To improve performance, a new approach called flow attention is introduced, which aligns with Kirchhoff's first law. Experiments on electronic circuits and power grids demonstrate that this method enhances the effectiveness of attention-based GNNs in classification and regression tasks.

Recent advancements in graph neural networks (GNNs) have highlighted their effectiveness in node classification tasks. However, traditional GNNs often neglect role-based characteristics that can enhance node representation learning. To overcome these limitations, a new model called the hypergraph neural network with state space model (HGMN) has been proposed, integrating role-aware representations and employing hypergraph construction techniques to capture complex relationships among nodes.

The article presents a novel approach to incomplete multi-view clustering (IMVC) through Dynamic Deep Graph Learning with Masked Graph Reconstruction Loss. It highlights the limitations of existing methods, particularly their reliance on K-Nearest Neighbors (KNN) and Mean Squared Error (MSE) loss, which can introduce noise and reduce graph robustness. The proposed method aims to enhance the effectiveness of IMVC by addressing these challenges, thereby contributing to the advancement of Graph Neural Networks (GNNs) in this field.

The article presents the Neighborhood-Aware Star Kernel (NASK), a new graph kernel for attributed graph learning. Attributed graphs, which feature irregular topologies and a mix of numerical and categorical attributes, are prevalent in areas like social networks and bioinformatics. NASK utilizes an exponential transformation of the Gower similarity coefficient to efficiently model these attributes and incorporates multi-scale neighborhood structural information through star substructures enhanced by Weisfeiler-Lehman iterations. The theoretical proof confirms that NASK is positive definite.

Graph neural networks (GNNs) are increasingly utilized in urban spatiotemporal forecasting, particularly for predicting infrastructure issues like potholes and rodent problems. Government inspection ratings provide insights into the state of incidents in various neighborhoods, but these ratings are limited to a sparse selection of areas. To enhance prediction accuracy, a new multiview, multioutput GNN model integrates both government ratings and crowdsourced reports, addressing biases in reporting behavior and improving the understanding of urban incidents.

The article discusses SemST, a new semantic-guided deep learning framework for clustering spatial transcriptomics data. This framework utilizes Large Language Models (LLMs) to interpret gene symbols, transforming them into biologically informed embeddings. By integrating these embeddings with spatial relationships through Graph Neural Networks (GNNs), SemST aims to enhance the understanding of gene expression in tissue microenvironments, achieving state-of-the-art clustering performance.
