achieves_planned_objective exponential transformation An exponential transformation is a data transformation consisting in the application of the exponential function with a given base a (where a>0 and a is typically not equal to 1) to a (one dimensional) real number input. For alternative definitions and properties of this function see, e.g., http://en.wikipedia.org/wiki/Exponential_function and http://en.wikipedia.org/wiki/Characterizations_of_the_exponential_function.
