Metaplectic Gabor frames of Wigner-Decomposable Distributions
Elena Cordero, Gianluca Giacchi
Metaplectic Wigner distributions generalize the most popular time-frequency representations, such as the short-time Fourier transform (STFT) and -Wigner distributions, using met…

Metaplectic Gabor Frames and Symplectic Analysis of Time-Frequency Spaces
Elena Cordero, Gianluca Giacchi
We introduce new frames, called \textit{metaplectic Gabor frames}, as natural generalizations of Gabor frames in the framework of metaplectic Wigner distributions. Namely, we devel…

On the determination of Lagrange Multipliers for a weighted LASSO problem using geometric and convex analysis techniques
Gianluca Giacchi, Bastien Milani, Benedetta Franchieschiello
Compressed Sensing (CS) encompasses a broad array of theoretical and applied techniques for recovering signals, given partial knowledge of their coefficients. Its applications span…
