Correction of Pooling Matrix Mis-specifications in Compressed Sensing Based Group Testing
Shuvayan Banerjee, Radhendushka Srivastava, James Saunderson +1
Compressed sensing, which involves the reconstruction of sparse signals from an under-determined linear system, has been recently used to solve problems in group testing. In a publ…
Robust Non-adaptive Group Testing under Errors in Group Membership Specifications
Shuvayan Banerjee, Radhendushka Srivastava, James Saunderson +1
Given samples, each of which may or may not be defective, group testing (GT) aims to determine their defect status by performing tests on `groups', where a group is for…
Dictionary-Based Reconstruction of Spatio-Temporal 3D Magnetic Field Images from Quantum Diamond Microscope
Anuj Bathla, Madhur Parashar, Matthew Markham +2
Three-dimensional magnetic imaging with high spatio-temporal resolution is critical for probing current paths in various systems, from biosensing to microelectronics. Conventional…
Fast Debiasing of the LASSO Estimator
Shuvayan Banerjee, James Saunderson, Radhendushka Srivastava +1
In high-dimensional sparse regression, the \textsc{Lasso} estimator offers excellent theoretical guarantees but is well-known to produce biased estimates. To address this, \cite{Ja…
