    • Efficient Sketches for Earth-Mover Distance, with Applications 

      Indyk, Piotr; Woodruff, David; Do Ba, Khanh; Andoni, Alexandr (Institute of Electrical and Electronics Engineers, 2010-03)
      We provide the first sub-linear sketching algorithm for estimating the planar Earth-Mover Distance with a constant approximation. For sets living in the two-dimensional grid [Δ][superscript 2], we achieve space ΔE for ...
