Seminars at the Faculty of Informatics

DATE: Tuesday, September 28th 2010
PLACE: USI Università della Svizzera italiana, room CC250, Main building (Via G. Buffi 13)
TIME: 13.30

In this talk we discuss the exact computation of derivatives using the technique of Algorithmic Differentiation (AD).
Complexity estimates for the two basic approaches, i.e.
the forward mode and the reverse mode, will be given.
This includes for example the "cheap gradient result", i.e.
that computational complexity for evaluating the gradient of a scalar-valued function can be bounded above by a computational complexity of the function evaluation multiplied by a small constant.
This upper bound allows the usage of exact gradient information for numerous optimization problems.
The exact derivative information in combination with structure exploitation allows the optimization of rather complicated processes and structures. Several examples will be shown in this talk including applications from aerodynamics and nuclear optics.
