“…There has been a surge of interest in recent years in applying low-rank techniques to seismic data problems, including interpolation (Ma, 2013;Kumar et al, 2015;Aravkin et al, 2014;Trickett et al, 2010), noise attenuation (Freire and Ulrych, 1988;Bekara and Van der Baan, 2007;Nazari Siahsar et al, 2016), estimation of primaries by sparse inversion (Jumah and Herrmann, 2014), simultaneous source deblending (Cheng and Sacchi, 2015;Kumar et al, 2016), and travel-time tomography (Stork, 1992). Extensions of these low-rank ideas to multi-dimensional tensors in the seismic context can be found in, e.g., Kreimer and Sacchi (2012), Kreimer et al (2013), Trickett et al (2013), Da .…”
