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..

Researcher Affiliation Academia 1Department of Computer Science&Engineering, Texas A&M University 2Department of Computer Science, University of Georgia 3Department of Computer Science, Rice University.
Pseudocode Yes Algorithm 1 Graphon Estimation ... Algorithm 2 G-Mixup ... Algorithm 3 G-Mixup (batch)
Open Source Code Yes Our code is available at https://github.com/ahxt/g-mixup.
Open Datasets Yes We evaluate the performance of G-Mixup ... with various datasets and GNN backbones in Section 5.3... Dataset IMDB-B IMDB-M REDD-B REDD-M5 REDD-M12... We experiment on molecular property prediction task (Hu et al., 2020), including ogbg-molhiv, ogbg-molbace, ogbgmolbbbp.
Dataset Splits Yes We split the dataset into train/val/test data by 7 : 1 : 2.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory specifications) used for running the experiments.
Software Dependencies No The paper mentions specific algorithms and models like 'Adam optimizer(Kingma & Ba, 2015)', 'GCN (Kipf & Welling, 2017)', 'GIN (Xu et al., 2018)', and refers to implementations like 'https://github.com/pyg-team/pytorch_geometric/blob/1.7.2/examples/gcn2_ppi.py'. However, it does not provide a list of ancillary software dependencies with specific version numbers (e.g., Python version, PyTorch version).
Experiment Setup Yes For model training, we use the Adam optimizer(Kingma & Ba, 2015). The initial learning rate is 0.01 and will drop the learning rate by half every 100 epochs. The batch size is set to 128. ... For hyperparemeter in G-Mixup, we generate 20% more graphs for training graph. The graphons are estimated based on the training graphs. We use different λ [0.1, 0.2] to mix up the graphon and generate synthetic with different strength of mixing up.
