| Research Type | Experimental | In the experiments, it is proved that our method can predict discrete values with high accuracy, very close to or even better than these values obtained by carefully tuned thresholds on Movielens and You Tube data sets. In this section, we apply our optimal discrete matrix completion method (ODMC) to two real world data sets: Movie Lens and You Tube data sets. |

| Pseudocode | Yes | Algorithm 1 Optimal Discrete Matrix Completion |
| Open Source Code | No | The paper does not contain any statement or link indicating that the source code for their methodology is publicly available. |
| Open Datasets | Yes | Movie Lens rating data are collected from Movie Lens website: https://movielens.org/. This data set was collected through Movie Lens website during the seven-month period from September 19th, 1997 through April 22nd, 1998. Please check more details at http://grouplens.org/. This You Tube data set (Zafarani and Liu 2009), is crawled from You Tube website on 2008... |
| Dataset Splits | Yes | Every time, we hold 75% of rated entries as observed training data, and the other 25% data as testing data. |
| Hardware Specification | No | The paper does not provide specific details about the hardware (e.g., CPU/GPU models, memory) used for running the experiments. |
| Software Dependencies | No | The paper does not specify version numbers for any software components, libraries, or solvers used in the experiments. |
| Experiment Setup | Yes | In this experiment, we use μ = μ0 kα , where μ0 is learned through small data set (Bottou 2010), and k means the number of iterations, α = 0.1 in the experiment. For SVD, GROUSE, OPTSPACE and ODMC, an exact low-rank value should be set, and we use {5, 10, 15, 20, 25} to tune the best rank approximation value for different matrix in the experiments. |
