Cyclic Coordinate Update Algorithms for Fixed-Point Problems: Analysis and Applications
Yat Tin Chow, Tianyu Wu, Wotao Yin
Many problems reduce to the fixed-point problem of solving . To this problem, we apply the coordinate-update algorithms, which update only one or a few components of at…

Unique determination of the index of refraction from phase-less near-field data in two dimensions
Yat Tin Chow, Fadil Santosa, Gunther Uhlmann
Motivated by non-destructive testing of optical fiber, we consider the problem of determining the index of refraction of a two-dimensional medium from magnitude of the total field…
