Sure, here it is. Automatic Differentiation is the process of translating one program that computes a function $f$ and generating a different program that computes the derivative of that function, $f'$. Activity analysis is important for AD. Our results show that a dynamic activity analysis, checking at run-time, incurs an average overhead of 27\% when all independent variable are active. When as few as half of the independent variables are active, dynamic activity analysis enables an average speedup of 28\%. We investigate static activity analysis combined with dynamic activity analysis as a technique for reducing the overhead of dynamic activity analysis. Jean's familiar with this project, so he can be a good arbiter of who would be appropriate referees.
