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 Our experiments with tensor network models explore this hypothesis by seeking compact representations that preserve decoding capacity while exploiting the possible latent structure of relational knowledge. In these experiments we evaluate the compression capabilities of both Simple Order3Network and Triangle Tensor Network models. We train these models on the dataset of Hernandez et al. [2023] until convergence and measure the faithfulness of the resulting decoder functions. Figure 1a summarizes the results by plotting the mean faithfulness against the parameter count of trained tensor network matrices.

Pseudocode No The paper describes mathematical formulations for tensor network architectures, such as: "T R s,o = Ts,r,ovr = X r,s ,r ,o vr P 2 r,r T 0 s ,r ,o P 1 s,s P 2 o,o". However, there are no explicit sections or figures labeled "Pseudocode" or "Algorithm" that provide structured, step-by-step procedures in a code-like format.
Open Source Code Yes 1Code and data are available at the project website: https://bit.ly/structure-of-relations.
Open Datasets Yes We use three datasets: 1) The Dataset of Hernandez et al. [2023]: it consists of 47 distinct, mostly orthogonal relations (i.e., fruit inside color and adjective antonym). 2) Extended Dataset: our extended version of the dataset of Hernandez et al. [2023] that introduces several new relations, allowing a better understanding of the relational structure. 3) Mathematical Dataset: a novel relational dataset containing mathematical operations (i.e., number plus 6 and number times 9) providing a more controlled, and in a sense a denser relational structure. For further information, we refer to Appendix D. We release the extended and the mathematical dataset under the MIT license.
Dataset Splits Yes Figure 4b: Faithfulness results for the mathematics dataset. Blue bars represent relations from the training set, purple bars from the test set split randomly with a ratio 75%-25% respectively. Figure 7: Sample-wise faithfulness results with tensor networks on the dataset of Hernandez et al. [2023]. All bars represent the test set for a given relation, after splitting all samples with a train-test ratio of 75%-25% respectively.
Hardware Specification Yes All experiments were run on an internal cluster of either Nvidia A100 40GB or Nvidia H100 NVL GPUs. All conducted experiments required cca. 5000 GPU hours.
Software Dependencies No The paper mentions specific language models used (GPT-J, Llama 3.1 8B, GPT-Neo X-20B) and discusses optimizers (SGD, Adam, Adam W), but it does not provide specific version numbers for software dependencies like Python, PyTorch, or CUDA, which are necessary for a reproducible software environment.
Experiment Setup Yes We performed a grid search for both models with dr {2, 4, 6, 8, 30, 100}, ds , do {10, 50, 100, 300}; for the Triangle Tensor Network we fixed dx, dy, dz {50}. We present all hyperparameters and their respective values in Table 4. We conducted a grid search using these values and selected the optimal optimizer, batch size, and learning rate indicated under the "Selected value" column to generate all figures in the paper.
