Community Detection using the Edge Laplacian Dynamics vis-a-vis Ricci Flow
Pratibha Bhandari, Soumyendu Raha
It has been found that utilizing the geometric properties of the graph dynamics can bring out crucial information of the data that a statistical analysis will not. The properties o…
Geometry-Consistent Bayesian Filtering under Structural Model Uncertainty: A Geometric Projection Particle Filter
Surya Ratna Prakash D, Soumyendu Raha
Nonlinear state estimation under structural model uncertainty remains a fundamental challenge in autonomous Guidance, Navigation, and Control (GNC) systems. Conventional Bayesian f…
Effective Resistance-Based Graph Sparsification and Community Detection
Jayanta Pari, Pratibha Bhandari, Soumyendu Raha
Community detection is a key task in network analysis, providing insight into the structural organization of complex systems. Effective resistance, a graph-theoretic metric derived…
Low Latency Stand Alone Compute-Efficient Forecasting of Marine Engine Time Series Data
Y. Harsha Vardhana Reddy, Soumyendu Raha
The operational reliability of a high performance marine vessel depends critically on the health of its marine propulsion systems, which are increasingly subjected to diverse opera…
Co-State Based Data Fusion and Risk Aware Filtering for Spacecraft Navigation and Hazard Prediction
Surya Ratna Prakash D, Soumyendu Raha
This paper develops a co-state based fusion frame work for spacecraft navigation, consistency monitoring, and hazard forecasting. A differential algebraic co-state is introduced as…
A graph based advection framework for climate-driven species distribution
Pranali Roy Chowdhury, Soumyendu Raha
Climate change is reshaping species interactions and movement across fragmented landscapes. Despite this, most mathematical models assume random diffusion, overlooking the influenc…
Transient Stability of Nonlinear Stochastic Dynamics: A Finite-Amplitude Logarithmic Measure Framework
Surya Ratna Prakash D, Soumyendu Raha
Spacecraft guidance, navigation, and control systems operating during mission-critical phases such as atmospheric entry, powered descent, and planetary landing require reliable ass…
