| Pseudocode | Yes | Algorithm 1 Subsampling Judgments |
| Open Source Code | Yes | All source code is available at https://github.com/YixuanEvenXu/quantitative-judgment-aggregation. |
| Open Datasets | Yes | We use the data from https://www.marathonguide.com/, which publishes results of all major marathon events. ... Codeforces (https://codeforces.com), a website hosting frequent online programming contests... |
| Dataset Splits | No | The paper states, 'We use the results of the first i − 1 contests to predict the results of the i-th contest,' which describes a temporal train/test split. However, it does not explicitly mention a separate validation set or how hyperparameters were tuned. |
| Hardware Specification | Yes | All experiments are done on a server with 56 CPU cores and 504G RAM. No GPU is used. |
| Software Dependencies | Yes | We use Gurobi Gurobi Optimization, LLC [2023] and Network X Hagberg et al. [2008] to implement ℓ1 QRJA and the least-square regression implementation in Sci Py [Jones et al., 2014] to implement ℓ2 QRJA. |
| Experiment Setup | No | The paper states that 'We set all weights to 1' and discusses variants of Matrix Factorization with 'r = 1, 2, 5' and the use of 'gradient descent for a fixed number of epochs on a deterministic initialization.' However, specific numerical hyperparameters like the learning rate or the exact number of epochs are not provided in the main text or appendices. |
