Exploiting Differentiable Programming for the End-to-end Optimization of Detectors
Résumé
The coming of age of differentiable programming makes possible today to create complete
computer models of experimental apparatus that include the stochastic data-generation processes, the full modeling of the reconstruction and inference procedures, and a suitably defined
objective function, along with the cost of any given detector configuration, geometry and materials. This enables the end-to-end optimization of the instruments, by using techniques developed
within computer science that are currently vastly exploited in fields such as fluid dynamics.
The MODE Collaboration has started to consider the problem in its generality, to provide
software architectures that may be useful for the optimization of experimental design. These
models may be useful in a ”human in the middle” system as they provide information on the
relative merit of different configurations as a continuous function of the design choices. In this
short contribution we summarize the plan of studies that has been laid out, and its potential in
the long term for the future of experimental studies in fundamental physics.
