Reverse differentiation and the inverse diffusion problem
(1997-06)
In this paper the task of solving the inverse photon diffusion problem in human tissue will be discussed. In such problems the optical properties of the tissue are to be determined from a knowledge of measured values of ...
Giving reverse differentiation a helping hand
(1997)
Reverse automatic differentiation provides a very low bound on the operations count for calculating a gradient of a scalar function in n dimensions but suffers from a high storage requirement. In this paper we will show ...
