| Research Type | Experimental | We compare this novel surrogate with competing approaches on 9 different datasets. Our method shows to be highly competitive in practice, outperforming the least squares loss on 7 out of 9 datasets. |

| Pseudocode | No | The paper focuses on theoretical analysis, proofs, and mathematical formulations. It describes algorithms conceptually but does not present any structured pseudocode blocks or clearly labeled algorithm sections. |
| Open Source Code | No | The paper does not contain any explicit statements about releasing the source code for the methodology described, nor does it provide a link to a code repository. |
| Open Datasets | Yes | The different datasets that we will consider are described in (Chu and Keerthi, 2005) and can be download from the authors website4. http://www.gatsby.ucl.ac.uk/~chuwei/ordinalregression.html. |
| Dataset Splits | Yes | Performance is computed as the squared error on left out data, averaged over 20 folds. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware (e.g., CPU, GPU models, memory) used for running the experiments. |
| Software Dependencies | No | The paper does not mention any specific software dependencies or their version numbers (e.g., programming languages, libraries, frameworks) used for the experiments. |
| Experiment Setup | No | The paper states that "the optimal values of w, θ were found by minimizing the empirical surrogate risk" and that "we did not consider the use of regularization." However, it does not provide specific hyperparameters like learning rate, batch size, or optimizer settings needed to reproduce the experiment. |
