| Pseudocode | Yes | Algorithm 1: Stochastic gradient descent; Algorithm 2: Targeted inference; Algorithm 3: Loss augmented inference |
| Open Source Code | No | The paper does not provide an explicit statement or a link to open-source code for the described methodology. |
| Open Datasets | Yes | We compare the error of k NN classifiers using metrics learned with our approach to that with other learned metrics. For this evaluation we replicate the protocol in [11], using the seven data sets in Table 1. |
| Dataset Splits | Yes | for the other five data sets, we report the mean and standard errors of 5-fold cross validation (results for all methods are on the same folds). [...] The value of C is tuned on on a 75%/25% split of the training portion. |
| Hardware Specification | No | The paper mentions running experiments but does not specify any hardware components (e.g., CPU, GPU models, memory). |
| Software Dependencies | No | The paper does not mention any specific software dependencies with version numbers. |
| Experiment Setup | Yes | Our SGD algorithm stops when the running average of the surrogate loss over most recent epoch no longer descreases substantially, or after max. number of iterations. We use learning rate η(t) = 1/t. [...] The value of C is tuned on on a 75%/25% split of the training portion. |
