Data Filtering for Cluster Analysis by $ℓ_{0}$ -Norm Regularization

Andrea Cristofari

A data filtering method for cluster analysis is proposed, based on minimizing a least squares function with a weighted $ℓ_{0}$ -norm penalty. To overcome the discontinuity of the o…

A Two-Stage Active-Set Algorithm for Bound-Constrained Optimization

Andrea Cristofari, Marianna De Santis, Stefano Lucidi +1

In this paper, we describe a two-stage method for solving optimization problems with bound constraints. It combines the active-set estimate described in [Facchinei and Lucidi, 1995…
