| Pseudocode | No | The paper describes its algorithms and equations, but does not include structured pseudocode or algorithm blocks. |
| Open Source Code | No | The paper does not contain any statement about releasing source code or provide links to a code repository. |
| Open Datasets | No | The paper uses simulated data from known dynamical systems, but does not provide concrete access information (link, DOI, repository, or citation) for the specific simulated datasets used in their experiments. |
| Dataset Splits | No | The paper describes how data was simulated (e.g., '20 trials'), but does not specify explicit training, validation, or test dataset splits in terms of percentages or counts for a defined dataset. |
| Hardware Specification | No | The paper does not provide any specific hardware details such as CPU/GPU models or memory specifications used for running its experiments. |
| Software Dependencies | No | The paper mentions using the 'forward Euler method' for solving ODEs but does not specify any software names with version numbers for its implementation or other dependencies. |
| Experiment Setup | Yes | In all experiments, we choose an exponentiated quadratic covariance function in the prior over the dynamics f and initialise the inducing point means and Jacobian matrices at zero. Each fixed point observation s uncertainty is initialised with a standard deviation of 0.1. We generate C and d by drawing their entries from Gaussian distributions unless otherwise stated, and initialise our algorithm at these parameter values. For inference, we solve the ODEs (19)-(22) using the forward Euler method with t = 1ms. Unless stated otherwise, the link function is the indentity g(z) = z. |
