HoT-SSM:Higher-order Temporal Knowledge Graph Reasoning with State Space Models for Health Care
Thummaluru Siddartha Reddy, Vempalli Naga Sai Saketh, Yash Punjabi +1
Medical knowledge graphs (MKGs) infused with clinical knowledge have been increasingly used to model electronic health records (EHRs) to support interpretable predictions in health…
Learning Long Range Spatio-Temporal Representations over Continuous Time Dynamic Graphs with State Space Models
Ayushman Raghuvanshi, Thummaluru Siddartha Reddy, Sundeep Prabhakar Chepuri +1
Continuous-time dynamic graphs (CTDGs) provide a richer framework to capture fine-grained temporal patterns in evolving relational data. Long-range information propagation is a key…
Clustering with Simplicial Complexes
Thummaluru Siddartha Reddy, Sundeep Prabhakar Chepuri, Pierre Borgnat
In this work, we propose a new clustering algorithm to group nodes in networks based on second-order simplices (aka filled triangles) to leverage higher-order network interactions.…
Sampling And Reconstruction Of Diffusive Fields On Graphs
Siddartha Reddy, Sundeep Prabhakar Chepuri
In this paper, the focus is on the reconstruction of a diffusive field and the localization of the underlying driving sources on arbitrary graphs by observing a significantly small…
