Polar Convolution
Michael P. Friedlander, Ives Macêdo, Ting Kei Pong
The Moreau envelope is one of the key convexity-preserving functional operations in convex analysis, and it is central to the development and analysis of many approaches for convex…
Low-rank spectral optimization via gauge duality
Michael P. Friedlander, Ives Macedo
Various applications in signal processing and machine learning give rise to highly structured spectral optimization problems characterized by low-rank solutions. Two important exam…
Gauge optimization and duality
Michael P. Friedlander, Ives Macedo, Ting Kei Pong
Gauge functions significantly generalize the notion of a norm, and gauge optimization, as defined by Freund (1987}, seeks the element of a convex set that is minimal with respect t…
