Reproducibility Variable Result LLM Response
Research Type Experimental In this section, we investigate the impact that the proposed MLE regularisation has on Dreamer V3. We show that the inclusion of this term reduces the chaotic state dynamics produced by the control policy and that this improved stability increases performance when noise is introduced. For these experiments, we train three instances of Dreamer V3 with MLE regularisation and reuse the SAC, TD3 and Dreamer V3 policies from Sections 3 & 4.
Researcher Affiliation Academia Rory Young Nicolas Pugeault School of Computing Science University of Glasgow
Pseudocode Yes Algorithm 1 MLE regularisation
Open Source Code Yes This paper provides open access to the code, with instructions to faithfully reproduce the main experimental results outlined in Sections 3 & 5 and Appendix A.2 & B.
Open Datasets Yes To closely match real-world applications, we estimate the stability of tasks from the Deep Mind Control Suite [27] when controlled by deep RL policies.
Dataset Splits No The paper does not explicitly provide training/test/validation dataset splits. It mentions 'evaluation episodes' but not a distinct validation set or split for hyperparameter tuning or model selection during training.
Hardware Specification Yes All models are based on the Stable Baselines 3 [18] implementation with the parameters outlined in Appendix A.2 and trained using an Intel Core i7-8700 CPU workstation with an Nvidia RTX 2080 Ti GPU and 32GB of RAM.
Software Dependencies No The paper mentions using 'Stable Baselines 3' but does not provide a specific version number for this software or any other key software components used in the experiments.
Experiment Setup Yes All models are based on the Stable Baselines 3 [18] implementation with the parameters outlined in Appendix A.2 and trained using an Intel Core i7-8700 CPU workstation with an Nvidia RTX 2080 Ti GPU and 32GB of RAM.
