The initial potential is defined to be formula_13. Since a constraint of each iteration is that the potential be held constant, the final potential is formula_14. Thus the final error is "likely" to be near formula_15. However, the final potential function is not the 0-1 loss error function. For the final error to be exactly formula_15, the variance of the loss function must decrease linearly w.r.t. time to form the 0-1 loss function at the end of boosting iterations. This is not yet discussed in the literature and is not in the definition of the algorithm below.
