Reproducibility Variable Result LLM Response
Research Type Experimental The experimental results and extensive ablation studies on the standard D4RL benchmark show that our method has a good representation ability for policies and achieves superior performance in most tasks.
Researcher Affiliation Academia 1Department of Automation, Tsinghua University 2Institute for Interdisciplinary Information Sciences, Tsinghua University 3Harbin Institute of Technology
Pseudocode Yes Algorithm 1: IQL+LPD algorithm
Open Source Code No The paper does not provide concrete access to source code for the methodology described. While it states 'We reproduce OPAL with authors providing code via email', this refers to a baseline, not their own method's code release.
Open Datasets Yes We evaluate our method on a suite of standard and challenging offline tasks (e.g., D4RL (Fu et al. 2020)) including Franka kitchen, Antmaze, and Adroit.
Dataset Splits No The paper mentions using D4RL tasks but does not specify how the data within these tasks are split into train/validation/test sets in the provided text.
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 does not provide specific ancillary software details with version numbers (e.g., library or solver names with version numbers like Python 3.8, CPLEX 12.4).
Experiment Setup Yes Each experiment result is averaged over five random seeds with a standard deviation. We test the performance of IQL+OPAL with the most suitable steps c {1, 10} and fine-tune the expectile ratio λ and temperature parameter β in IQL. We ran IQL+LPD on kitchen-partial-v0 with various parameters, such as the expectile ratio λ [0.45, 0.9] and the temperature β [0.35, 0.8].
