| Reproducibility Variable | Result | LLM Response |
|---|---|---|
| Research Type | Experimental | The proposed method is evaluated using both synthetic and real climate data which demonstrate its ability to accurately predict data missing in spatial regions over time. |
| Researcher Affiliation | Academia | 1Uppsala University, Sweden. |
| Pseudocode | Yes | A pseudocode implementation is provided in Algorithm 1. |
| Open Source Code | Yes | Code available at github. |
| Open Datasets | Yes | Synthetic data is generated over a uniform grid and a subset of N = 700 training points are used. (Section 5.1) Here we set N = 63 503 as the number of training points. (Section 6.1) We use tropical pacific Sea Surface Temperature (SST) data (Wikle, 2011). (Section 6.1) We use precipitation data from the Climate Research Unit (CRU) time series datasets of climate variations (Jones & Harris, 2013). (Section 6.2) |
| Dataset Splits | No | The paper mentions training and testing data but does not explicitly describe a separate validation set or its split. |
| Hardware Specification | No | The paper does not provide specific details about the hardware used for the experiments, such as CPU/GPU models or memory. |
| Software Dependencies | No | The paper does not provide specific version numbers for any software dependencies or libraries used in the experiments. |
| Experiment Setup | Yes | For the proposed method with Nt = 25, Ns = 15 and a spatial basis support set to L = 5 spatial units. This results in φ(s, t) being of dimension p = Ns(Nt + 1) = 390. (Section 5.1) For the proposed method we use Nt = 35, Ns = 15 and a support of L = 3 for the spatial basis, so that p = Ns(Nt + 1) = 540. (Section 5.2) |
