Pseudocode Yes Algorithm 1 Solving Problem (4) by Inexact ALM
Open Source Code No The paper does not provide any links to open-source code or explicitly state that the code will be made publicly available.
Open Datasets Yes We evaluate our approach on three public databases: the Extended Yale B database (Georghiades, Belhumeur, and Kriegman 2001) (Lee, Ho, and Kriegman 2005), the AR database (Martinez and Benavente. 1998) and the ORL database (Samaria and Harter 1994).
Dataset Splits Yes Following the protocol in DSLR (Zhang, Jiang, and Davis 2013), we first randomly select Nc images for each person as training images (Nc = 8, 32), and the rest as testing images.
Hardware Specification Yes All the experiments are performed on matlab with computer configuration as follows, CPU: i5-2400 3.10GHz RAM:14.0GB.
Software Dependencies No The paper states 'All the experiments are performed on matlab' but does not specify the version of Matlab or any other software dependencies with version numbers.
Experiment Setup Yes Input: Feature Matrix X, parameter λ and α 1: Initialize: Z0 = 0, J0 = 0, E0 = 0, Y 0 1 = 0, Y 0 2 = 0, µ0 = 10 5, µmax = 108, ρ = 1.1, ε = 10 6
