# Phase retrieval

I’ve got the power. / Like the crack of the whip/ I snap attack/ Front to back

January 17, 2017 — November 8, 2019

feature construction

Hilbert space

machine learning

model selection

neural nets

optimization

You know the power of the signal; what is the phase? Griffin-Lim algorithm, Wirtinger flow methods based on Wirtinger calculus, Phase-gradient heap integration (Pru and Søndergaard 2016).

TODO: investigate Yue M Lu’s work on phase retrieval as an important example in a large classe of somewhat- analytically-understood nonconvex problems, starting from his recent slide deck on that theme.
