| Pseudocode | Yes | Algorithm 1 Geo Phy algorithm |
| Open Source Code | Yes | Our implementation is found at https://github.com/m1m0r1/geophy |
| Open Datasets | Yes | We compared the marginal log-likelihood (MLL) estimates for the eight real datasets (DS1-8) [8, 6, 37, 9, 17, 43, 38, 30]. |
| Dataset Splits | No | The paper does not explicitly describe train/validation/test splits for its own model training in the conventional supervised learning sense. It performs inference on the entire given datasets. |
| Hardware Specification | Yes | We measured CPU runtimes using a single thread on a 20-core Xeon processor. |
| Software Dependencies | Yes | we replicated the Mr Bayes SS runs using Mr Bayes version 3.2.7a. |
| Experiment Setup | Yes | In all of our experiments, we used Adam optimizer with an initial learning rate of 0.0001. The learning rate was then multiplied by 0.75 after every 200,000 steps. Similar to approaches taken by Zhang and Matsen IV [42], we incorporated an annealing procedure during the initial consumption of 100,000 MC samples. Specifically, we replaced the likelihood function in the lower bound with P(Y |Bτ, τ)β and linearly increased the inverse temperature β from 0.001 to 1 throughout the iterations. |
