Physicists aim to reconstruct the distribution of physical quantities from the vast amounts of data collected by telescopes, as a means to better understand the physical processes of the Universe. This
reconstruction involves solving an inverse problem, specifically the Fredholm integral equation highlighted in the overview of this workshop. Methods for finding such a solution are not only...

12. Diagonalizing the Unfolding Problem

Assuming that the detector response is known and linear, and that indivdual events are IID distributed measurements, the continuous unfolding problem can be formulated as an infinite dimensional eigenvalue problem. This representation identifies the observable features of the unknown truth and quantifies the information content of a given measurement. The talk will present the underlying math...
