Phase retrieval via media diversity
Yan Cheng, Kui Ren, Nathan Soedjak
This work studies phase retrieval for wave fields, aiming to recover the phase of an incoming wave from multi-plane intensity measurements behind different types of linear and nonl…

A Policy Iteration Method for Inverse Mean Field Games
Kui Ren, Nathan Soedjak, Shanyin Tong
We propose a policy iteration method to solve an inverse problem for a mean-field game (MFG) model, specifically to reconstruct the obstacle function in the game from the partial o…

Reconstructing a state-independent cost function in a mean-field game model
Kui Ren, Nathan Soedjak, Kewei Wang +1
In this short note, we consider an inverse problem to a mean-field games system where we are interested in reconstructing the state-independent running cost function from observed…
