Dictionary Learning for the Almost-Linear Sparsity Regime

Alexei Novikov, Stephen White

Dictionary learning, the problem of recovering a sparsely used matrix $D \in R^{M \times K}$ and $N$ $s$ -sparse vectors $x_{i} \in R^{K}$ from sam…

Support Recovery for Sparse Multidimensional Phase Retrieval

Alexei Novikov, Stephen White

We consider the \textit{phase retrieval} problem of recovering a sparse signal $x$ in $R^{d}$ from intensity-only measurements in dimension $d \geq 2$ . Phase retrie…
