Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in [1].

Reproducibility Variable Result LLM Response
Research Type Experimental Experimentally, in challenging rich-observation environments, we show that our approach outperforms a state-of-the-art hybrid RL baseline which only relies on off-policy policy optimization, demonstrating the empirical benefit of combining on-policy and off-policy learning.

Pseudocode Yes Algorithm 1 Hybrid Actor-Critic (HAC) ... Algorithm 2 Hybrid Fitted Policy Evaluation (HPE) ... Algorithm 3 Hybrid NPG with Parameterized Policies (HNPG) ... Algorithm 4 Practical Finite-Horizon HNPG ... Algorithm 5 Finite-Horizon Hybrid Fitted Policy Evaluation (FHPE)
Open Source Code Yes Our code is publicly available at https://github.com/Yifei Zhou02/HNPG.
Open Datasets Yes In the Cifar100 augmented combination lock setting, the RL agent can only access images from the training set during training and will be tested using images from the test set. (Krizhevsky, 2009).
Dataset Splits No The paper mentions using "training set" and "test set" for the Cifar100 dataset, but does not explicitly provide details about a validation split (percentages, sample counts, or methodology).
Hardware Specification No The paper does not provide specific hardware details (e.g., exact GPU/CPU models, processor types, or memory amounts) used for running its experiments.
Software Dependencies No The paper mentions using 'multi-layer perceptron', 'Generalized Advantage Estimation (GAE)', and 'conjugate gradient algorithm', but does not provide specific software names with version numbers (e.g., Python, PyTorch, TensorFlow versions) required to replicate the experiment.
Experiment Setup Yes The pseudocode and hyperparameters are provided in Appendix E. We provide the hyperparameters of HNPG for both continuous Comblock and image-based continuous Comblock in Table 1. In addition, we provide the hyperparameters we tried for RLPD baseline for both Comblock settings in Table 2.
