| Reproducibility Variable | Result | LLM Response |
|---|---|---|
| Research Type | Experimental | Extensive experiments on several face image databases illustrate that our method is overall superior to the other robust PCA algorithms, such as PCA, PCA-L1 greedy, PCA-L1 nongreedy and HQ-PCA. |

| Pseudocode | Yes | Algorithm 1: Angle PCA |
| Open Source Code | No | The paper does not provide any statements about releasing open-source code or links to a code repository for the methodology described. |
| Open Datasets | Yes | We validate our approach on three face databases (Extended Yale B, CMU PIE and AR) and compared it with traditional PCA [Turk and Pentland, 1991] and recently proposed robust PCA methods including PCA-L1 greedy [Kwak, 2008], PCA-L1 non-greedy [Nie et al., 2011], and HQ-PCA [He et al., 2011]. |
| Dataset Splits | No | The paper describes training and testing splits for the datasets (e.g., '32 images, which include 7 noisy images, per person for training, and the remaining images for testing'). However, it does not explicitly mention or specify any separate validation dataset splits. |
| Hardware Specification | No | The paper does not provide specific details about the hardware (e.g., CPU, GPU models, memory) used to run the experiments. |
| Software Dependencies | No | The paper mentions the use of 'Matlab function' for data construction, but it does not list specific software dependencies with version numbers for the implementation or experiments. |
| Experiment Setup | Yes | In our experiments, we use 1-nearest neighbor (1NN) for classification and set the number of projection vectors from 10 to 200. ... To be fair, we set the number of projection vectors 400, and set the number of iteration 20. |
