Multiscale Attention Wavelet Neural Operator for Capturing Steep Trajectories in Biochemical Systems

AAAI 2024technical

In biochemical modeling, some foundational systems can exhibit sudden and profound behavioral shifts, such as the cellular signaling pathway models, in which the physiological responses promptly react to environmental changes, resulting in steep changes in their dynamic model trajectories. These ste…

Self-Promoted Clustering-based Contrastive Learning for Brain Networks Pretraining

IJCAI 2024poster

Rapid advancements in neuroimaging techniques, such as magnetic resonance imaging (MRI), have facilitated the acquisition of the structural and functional characteristics of the brain. Brain network analysis is one of the essential tools for exploring brain mechanisms from MRI, providing valuable in…

Simple Contrastive Multi-View Clustering with Data-Level Fusion

IJCAI 2024poster

Previous deep multi-view clustering methods usually design un-shared encoders to explore the cluster information among multi-view data, but they are difficult to customize the encoders for individual views and easily increase information loss. To address these issues, we propose a simple yet effecti…

Totally Dynamic Hypergraph Neural Networks

IJCAI 2023poster

Recent dynamic hypergraph neural networks (DHGNNs) are designed to adaptively optimize the hypergraph structure to avoid the dependence on the initial hypergraph structure, thus capturing more hidden information for representation learning. However, most existing DHGNNs cannot adjust the hyperedge n…

Information Augmentation for Few-shot Node Classification

IJCAI 2022poster

Although meta-learning and metric learning have been widely applied for few-shot node classification (FSNC), some limitations still need to be addressed, such as expensive time costs for the meta-train and difficult of exploring the complex structure inherent the graph data. To address in issues, th…

Multi-graph Fusion for Functional Neuroimaging Biomarker Detection

IJCAI 2020poster

Brain functional connectivity analysis on fMRI data could improve the understanding of human brain function. However, due to the influence of the inter-subject variability and the heterogeneity across subjects, previous methods of functional connectivity analysis are often insufficient in capturing…
