A Homotopy Coordinate Descent Optimization Method for $l_{0}$ -Norm Regularized Least Square Problem

Zhenzhen Sun, Yuanlong Yu

This paper proposes a homotopy coordinate descent (HCD) method to solve the $l_{0}$ -norm regularized least square ( $l_{0}$ -LS) problem for compressed sensing, which combine the homotop…

Robust Multi-class Feature Selection via $l_{2, 0}$ -Norm Regularization Minimization

Zhenzhen Sun, Yuanlong Yu

Feature selection is an important data pre-processing in data mining and machine learning, which can reduce feature size without deteriorating model's performance. Recently, sparse…
