| Research Type | Experimental | Specifically, we show both theoretically and via an extensive empirical evaluation that the SNR of the gradient estimates for the latent variable s variational parameters decreases as the number of importance samples increases. |

| Dataset Splits | No | The paper states '20 random train-test splits' but does not explicitly mention a separate validation set or its split percentage. |
| Hardware Specification | No | The paper does not provide specific hardware details (e.g., GPU/CPU models, memory amounts) used for running its experiments. |
| Software Dependencies | No | The paper mentions open-source code availability but does not specify software dependencies with version numbers (e.g., Python, PyTorch, TensorFlow versions). |
| Experiment Setup | Yes | For these experiments, we consider a two-layer DGP with the hyperparameters that directly affect the SNR the number of importance samples K and the minibatch size set to 50 and 64, respectively. |
