Pseudocode No The paper does not contain any explicit pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any statement or link indicating that its source code is publicly available.
Open Datasets Yes We test our method on three environments: Inverted Pendulum and Cart Pole from Open AI Gym (Brockman et al., 2016), and a Type-1 Diabetes medical treatment simulator.1 (...) 1 https://github.com/jxx123/simglucose.
Dataset Splits Yes The bandwidth of k and k are selected to make sure the function Bellman loss is not large on a validation set.
Hardware Specification No The paper does not provide specific details about the hardware used for experiments (e.g., GPU/CPU models, memory).
Software Dependencies No The paper mentions using 'PPO (Schulman et al., 2017)' as a policy training method but does not specify software dependencies with version numbers (e.g., Python, PyTorch, or specific library versions).
Experiment Setup Yes For horizon lengths, We fix γ = 0.95 and set horizon length H = 50 for Inverted-Pendulum, H = 100 for Cart Pole, and H = 50 for Diabetes simulator. (...) We take both kernels to be Gaussian RBF kernel and choose r Q and the bandwidths of k and k using the procedure in Appendix H.2. We use a fast approximation method to optimize ω in F + Q(ω) and F Q (ω) as shown in Appendix D.
