BSAM DATASETS

All multimodal recommendation datasets used in the manuscript Enhancing Robustness and Generalization Capability for Multimodal Recommender Systems via Sharpness-Aware Minimization (BSAM), which includes five Amazon datasets. Each dataset includes both visual and textual modalities. Baby, Sports, Clothing, Pet, and Office from Amazon. All the datasets comprise textual and visual features in the form of item descriptions and images. Our data preprocessing methodology follows the approach outlined in the MMRec Framework. We follow the popular evaluation setting with random data splitting 8:1:1 for training, validation, and testing. We filter out all the missing modality information to ensure all item has both visual and textual modalities.
