It is interesting to note that the power transformations will here be applied on the posterior classification probabilities p C θ instead of categorical probabilities p θ .
the three divergences presentend in Section 3 are defined on positive measures: in theory, we can simply use the exp function on the scores s θ and do not need to normalize them: neither the α and β divergences are scale invariant (see right column of table 1 and Cichocki and Amari 2010).
