Matrix Completion of World Trade
Gnecco Giorgio, Nutarelli Federico, Riccaboni Massimo
This work applies Matrix Completion (MC) -- a class of machine-learning methods commonly used in the context of recommendation systems -- to analyse economic complexity. MC is appl…
On principal component analysis of the convex combination of two data matrices and its application to acoustic metamaterial filters
Giorgio Gnecco, Andrea Bacigalupo
In this short paper, a matrix perturbation bound on the eigenvalues found by principal component analysis is investigated, for the case in which the data matrix on which principal…
Principal Component Analysis Applied to Gradient Fields in Band Gap Optimization Problems for Metamaterials
Giorgio Gnecco, Andrea Bacigalupo, Francesca Fantoni +1
A promising technique for the spectral design of acoustic metamaterials is based on the formulation of suitable constrained nonlinear optimization problems. Unfortunately, the stra…
