Pseudocode No The paper describes the proposed method in detail but does not include a clearly labeled pseudocode or algorithm block.
Open Source Code No The paper does not provide any statement or link indicating that the source code for the described methodology is publicly available.
Open Datasets Yes PIE Face Image Data Set This data set used in this experiment consist of 11554 gray face images from 68 people, which were captured under various poses, illumination conditions and expressions (Sim et al., 2003; Cai et al., 2007). MNIST Handwritten Digit Data Set This data set consists of 70, 000 grey images of scanned handwritten digits (Le Cun et al., 1998).
Dataset Splits No The paper describes how X and Y are formed for each dataset, but it does not provide specific train/validation/test dataset splits (e.g., percentages or counts) or a clear splitting methodology for reproducing model evaluation results.
Hardware Specification Yes All experiments are performed on a workstation with Intel(R) Core(TM) i7-4930K 3.40 GHz CPU and 64G RAM
Software Dependencies No The paper mentions using specific algorithms like APG and ADMM, but it does not provide specific version numbers for any software libraries, programming languages, or other dependencies used in the experiments.
Experiment Setup Yes On each data set, we run the solver without and with SSS to optimize Eq. (2) along a sequence of 100 values of λ equally spaced on the logarithmic scale of λ/λmax from 0.001 to 0.95.
