Pseudocode Yes Algorithm 1 Sinkhorn-Knopp Algorithm
Open Source Code Yes The code is available at https://anonymous.4open.science/r/CALBRec-A291.
Open Datasets Yes Datasets. We selected three real-world bundle recommendation datasets that represent diverse bundle recommendation scenarios: Youshu [Chen et al., 2019b] for book bundles; Net Ease [Cao et al., 2017a] for music playlists, and i Fashion [Chen et al., 2019c] for fashion outfits.
Dataset Splits Yes Following [Ma et al., 2022; Chang et al., 2020; Deng et al., 2020], we split each dataset into training/validation/testing sets at a 7:1:2 proportion.
Hardware Specification Yes All the models were trained using Pytorch and NVIDIA Titan-V GPUs.
Software Dependencies No The paper mentions 'Pytorch' but does not specify a version number. No other software dependencies are mentioned with specific version numbers.
Experiment Setup Yes For all methods, the embedding size was set as 64, Xavier normal initialization was adopted, the models were optimized using Adam optimizer with the learning rate 0.001, and the batch size was set as 2048. ... We set k to 20. ... Based on these empirical findings, we configure K as 300, 2000, and 2000 for Youshu, Net Ease and i Fashion, respectively.
