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 Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Reproducibility Variable Result LLM Response
Research Type Experimental To empirically validate our proposed technique, we first show that it can provide a way to combat underspecification in simulated control problems, inferring and optimizing user-specific reward functions. Next, we conduct experiments on pluralistic language datasets representing diverse user preferences and demonstrate improved reward function accuracy.

Pseudocode Yes Algorithm 1 Learning Multimodal Reward Functions using VPL, Algorithm 2 Policy Optimization using IQL and VPL, Algorithm 3 Policy Optimization using IQL and SPO + VPL
Open Source Code No We do not provide immediate access to the data and code, but will do so in the future.
Open Datasets Yes Maze-Navigation. This task is adapted from the 'maze2d-medium-v2' environment from the D4RL benchmark [27]. Ravens-Manipulation This task is adapted from the ravens benchmark [70]. Habitat-Rearrange This is a task based on the Meta Habitat simulator [68]. Ultra Feedback [20] dataset.
Dataset Splits No The paper describes data sampling and processing for context sets (e.g., 'randomly sample a smaller subset of K data points' and 'get 8 samples from the context set'), but does not explicitly define training, validation, and test dataset splits with percentages or counts for its experiments.
Hardware Specification Yes Computational Resources 2 RTX4090, 4 A100
Software Dependencies No The paper mentions 'Optimizer Adam (Kingma & Ba, 2015)' but does not provide specific version numbers for software libraries, frameworks, or programming languages used in the experiments.
Experiment Setup Yes Table 2: Hyperparameters for learning reward models using VPL. We sweep over these values and report the best results on 5 seeds. Table 3: Hyperparameters for IQL. We use the same parameters across all experiments. Table 4: Hyperparameters for LLM experiments
