Quantifying Uncertainties in the 2004 Sumatra-Andaman Earthquake Source Parameters by Stochastic Inversion
Devaraj Gopinathan, Mamatha Venugopal, Debasish Roy +3
Usual inversion for earthquake source parameters from tsunami wave data incorporates subjective elements. Noisy and possibly insufficient data also results in instability and non-u…
A Stochastically Evolving Non-local Search and Solutions to Inverse Problems with Sparse Data
Mamatha Venugopal, Ram Mohan Vasu, Debasish Roy
Building upon our earlier work of a martingale approach to global optimization, a powerful stochastic search scheme for the global optimum of cost functions is proposed on the basi…
An ensemble Kushner-Stratonovich-Poisson filter for recursive estimation in nonlinear dynamical systems
Mamatha Venugopal, Ram Mohan Vasu, Debasish Roy
Despite the numerous applications that may be expeditiously modelled by counting processes, stochastic filtering strategies involving Poisson-type observations still remain somewha…
A New Evolutionary Bayesian Approach Incorporating Additive Path Correction for Nonlinear Inverse Problems
M Venugopal, D Roy, R M Vasu
An evolutionary form of a generalized Bayesian update method, which is strictly derivative- free yet directed through an additive update term based purely on the statistical moment…
A Kushner-Stratonovich Monte Carlo Filter Applied to Nonlinear Dynamical System Identification
S Sarkar, S R Chowdhury, M Venugopal +2
A Monte Carlo filter, based on the idea of averaging over characteristics and fashioned after a particle-based time-discretized approximation to the Kushner-Stratonovich (KS) nonli…
