Pseudocode Yes Algorithm 1 Non-greedy 1-norm maximization.
Open Source Code No The paper does not provide explicit statements or links for open-source code for the described methodology.
Open Datasets Yes Specifically, the reconstruction errors with respect to nine different reduced dimensions from 10 to 50 are reported over 5 benchmark data sets, including the Japanese Female Facial Expression Database (JAFFE) [Dailey et al., 2010], UMIST face data set [Wechsler et al., 2012], the ORL database of faces [Cai et al., 2007], Columbia Object Image Library-20 (COIL-20) data set [Nene et al., 1996] and the USPS handwritten digit database [Liu et al., 2003]. All of the image data sets are downloaded from different web sites.
Dataset Splits Yes We randomly select half of the images from each object to form the training set and retain the rest as testing set for both of the data sets.
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments.
Software Dependencies No The paper does not provide specific software dependencies with version numbers.
Experiment Setup Yes randomly select 20% images to be occluded with randomly place of 1/4 size for fair comparison. We randomly select half of the images from each object to form the training set and retain the rest as testing set for both of the data sets. To illustrate the robustness of 2DRPCA-AOM, we corrupt a varying percentage of training images with outliers and recognize testing face images in the reduced space with the nearest neighbor (NN) classifier.
