A sparsity-based nonlinear reconstruction method for two-photon photoacoustic tomography
Madhu Gupta, Rohit Kumar Mishra, Souvik Roy
We present a new nonlinear optimization approach for the sparse reconstruction of single-photon absorption and two-photon absorption coefficients in photoacoustic tomography (PAT).…
Elementary Cellular Automata along with delay sensitivity can model communal riot dynamics
Souvik Roy, Abhik Mukherjee, Sukanta Das
This work explores the potential of elementary cellular automata to model the dynamics of riot. Here, to model such dynamics, we introduce probabilistic loss of information and del…
A New Estimation Algorithm for Box-Cox Transformation Cure Rate Model and Comparison With EM Algorithm
Suvra Pal, Souvik Roy
In this paper, we develop a new estimation procedure based on the non-linear conjugate gradient (NCG) algorithm for the Box-Cox transformation cure rate model. We compare the perfo…
A New Non-Linear Conjugate Gradient Algorithm for Destructive Cure Rate Model and a Simulation Study: Illustration with Negative Binomial Competing Risks
Suvra Pal, Souvik Roy
In this paper, we propose a new estimation methodology based on a projected non-linear conjugate gradient (PNCG) algorithm with an efficient line search technique. We develop a gen…
Sparse reconstruction of log-conductivity in current density impedance tomography
Madhu Gupta, Rohit Kumar Mishra, Souvik Roy
A new non-linear optimization approach is proposed for the sparse reconstruction of log-conductivities in current density impedance imaging. This framework comprises of minimizing…
