Using a recent convex formulation of IBM Model 2, we propose a new initialization scheme which has some favorable compar- isons to the standard method of initializing IBM Model 2 with IBM Model 1. Addition- ally, we derive the Viterbi alignment for the convex relaxation of IBM Model 2 and show that it leads to better F-Measure scores than those of IBM Model 2.
