Accelerating Frank-Wolfe via Averaging Step Directions
Zhaoyue Chen, Yifan Sun
The Frank-Wolfe method is a popular method in sparse constrained optimization, due to its fast per-iteration complexity. However, the tradeoff is that its worst case global converg…
Approximate methods for phase retrieval via gauge duality
Ron Estrin, Yifan Sun, Halyun Jeong +1
We consider the problem of finding a low rank symmetric matrix satisfying a system of linear equations, as appears in phase retrieval. In particular, we solve the gauge dual formul…
Polar Alignment and Atomic Decomposition
Zhenan Fan, Halyun Jeong, Yifan Sun +1
Structured optimization uses a prescribed set of atoms to assemble a solution that fits a model to data. Polarity, which extends the familiar notion of orthogonality from linear se…
Bundle methods for dual atomic pursuit
Zhenan Fan, Yifan Sun, Michael P. Friedlander
The aim of structured optimization is to assemble a solution, using a given set of (possibly uncountably infinite) atoms, to fit a model to data. A two-stage algorithm based on gau…
