Inference of Black Hole Fluid-Dynamics From Sparse Interferometric Measurements

ICCV 2021poster

We develop an approach to recover the underlying properties of fluid-dynamical processes from sparse measurements. We are motivated by the task of imaging the stochastically evolving environment surrounding black holes, and demonstrate how flow parameters can be estimated from sparse interferometric…

Fixed-Rank Approximation of a Positive-Semidefinite Matrix from Streaming Data

NeurIPS 2017poster

Several important applications, such as streaming PCA and semidefinite programming, involve a large-scale positive-semidefinite (psd) matrix that is presented as a sequence of linear updates. Because of storage limitations, it may only be possible to retain a sketch of the psd matrix. This paper de…
