Given the spectral graph clustering optimization problem Find y that minimizes y Ly yy=n and 1¹y = 0, which of the following optimization problems produce a vector y that leads to the same sweep cut as the optimization problem above? M is a diagonal mass matrix with different masses on the diagonal. Minimize y™ Ly A: subject to and Minimize y O B: subject to and y¹y = 1 1¹y = 0 subject to Ly Vi, yi= 1 or y; = -1 1¹y = 0 C: Minimize y¹ Ly/(yy) subject to 1¹y = 0 Minimize y™ Ly OD: subject to and y My = 1 1TMy = 0
