Fast signal recovery from quadratic measurements
Miguel Moscoso, Alexei Novikov, George Papanicolaou +1
We present a novel approach for recovering a sparse signal from cross-correlated data. Cross-correlations naturally arise in many fields of imaging, such as optics, holography and…
Generalized correlation based Imaging for satellites
Matan Leibovich, George Papanicolaou, Chrysoula Tsogka
We consider imaging of fast moving small objects in space, such as low earth orbit satellites. The imaging system consists of ground based, asynchronous sources of radiation and se…
Traveling waves in a mean field learning model
George Papanicolaou, Lenya Ryzhik, Katerina Velcheva
Lucas and Moll have proposed a system of forward-backward partial differential equations that model knowledge diffusion and economic growth. It arises from a microscopic model of l…
PCA for Implied Volatility Surfaces
Marco Avellaneda, Brian Healy, Andrew Papanicolaou +1
Principal component analysis (PCA) is a useful tool when trying to construct factor models from historical asset returns. For the implied volatilities of U.S. equities there is a P…
Synthetic aperture imaging and motion estimation using tensor methods
Matan Leibovich, George Papanicolaou, Chrysoula Tsogka
We consider a synthetic aperture imaging configuration, such as synthetic aperture radar (SAR), where we want to first separate reflections from moving targets from those coming fr…
