WebDec 5, 2013 · We smooth the classic optimal transport problem with an entropic regularization term, and show that the resulting optimum is also a distance which can be computed through Sinkhorn's matrix scaling algorithm at a speed that is several orders of magnitude faster than that of transport solvers. WebOptimal Transport Distance Between r and c Given a d×dcost matrix M, the cost of mapping r to c using a transport matrix (or joint probability) P can be quantified as hP,M i. The problem defined in Equation (1) dM(r,c) := min P∈U(r,c) hP,M i. (1) is called an optimal transport (OT) problem between r and c given cost M. An optimal table P⋆
