Trend filtering – I. A modern statistical tool for time-domain astronomy and astronomical spectroscopy [PDF]

Monthly notices of the Royal Astronomical Society, 2019
The problem of denoising a 1D signal possessing varying degrees of smoothness is ubiquitous in time-domain astronomy and astronomical spectroscopy. For example, in the time domain, an astronomical object may exhibit a smoothly varying intensity that is
