| Research Type | Experimental | Experiments are performed on multiple real-world datasets which show improvements over five widely used methods on predictive performance. The results also indicate that for classification MGPC is significantly better than the regression model with mixtures of GPs, different from the existing consensus that their single model counterparts are comparable. |

| Pseudocode | No | The paper does not include a pseudocode block or algorithm labeled as such. |
| Open Source Code | No | The paper does not provide any statement about making the source code available, nor does it include a link to a code repository. |
| Open Datasets | Yes | Table 1 shows the information about the used datasets. All of the datasets are available on UCI data repository [Lichman, 2013]. |
| Dataset Splits | Yes | All of the datasets are randomly split into the training, validation and test set by a ratio of 4:3:3. The truncation level T and the initializations for variance parameters of q(fn) are selected using the validation set. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware used to run the experiments (e.g., CPU/GPU models, memory, cloud instances). |
| Software Dependencies | No | The paper mentions using Python packages (e.g., scikit-learn for SVM), but does not specify any software names with version numbers for reproducibility (e.g., Python version, specific library versions). |
| Experiment Setup | Yes | The truncation level T and the initializations for variance parameters of q(fn) are selected using the validation set. T is set to range from 2 to 4, and the corresponding size of the support set for each component is set to Ntrain/T. The variance σn are initially set to range in 0.005 [1, 2, 4, 8, 16, 32]. |
