Cuevas-Tello, Juan C., Tino, Peter, Raychaudhury, Somak, Yao, Xin, Harva, Markus
We study the problem of estimating the time delay between two signals representing delayed, irregularly sampled and noisy versions of the same underlying pattern. We propose and demonstrate an...
Estimating Time Delay in Gravitationally Lensed Fluxes (2009)
Tino, Peter, Cuevas-Tello, Juan C., Raychaudhury, Somak
We study the problem of estimating the time delay between two signals representing delayed, irregularly sampled and noisy versions of the same underlying pattern. We propose a kernel-based technique...
How accurate are the time delay estimates in gravitational lensing? (2006)
Cuevas-Tello, Juan C., Tino, Peter, Raychaudhury, Somak
We present a novel approach to estimate the time delay between light curves of multiple images in a gravitationally lensed system, based on Kernel methods in the context of machine learning. We...
