Mixed Assignment We next define the concept of a mixed assignment: Definition 1.
for a training pair (x, y) and a predicted label y * ∈ Y(x), y * = y, a mixed assignment (M A) vector denoted as m J (y * , y) is defined with respect to J ∈ JJ x as follows: a mixed assignment is a new label, derived from the predicted label y * , that is identical to y * in all indexes in J and to y otherwise.
