Based on the article: A Fast, Compact Approximation of the Exponential Function by Nicol N.
Schraudolph and on the slighly modified version: On a Fast, Compact Approximation of the Exponential Function Neural Computation archive Volume 12 , Issue 9 (September 2000) Pages 2009-2012 Author: Gavin C. Cawley University of East Anglia, Norwich, Norfolk NR4 7TJ, England This is actually a bit faster than a LookupTable with linear interpolation, however it seems less accurate with error as big as a few % for some values of y.
