Dataset Description: Frappe Processed Dataset

The Frappe dataset has been processed to refine the quality of user-item interactions by removing entries where either users or items had fewer than 5 interactions. This pruning resulted in a significant reduction in the dataset size:

Number of Users: 651 (a reduction of 31.97% from the original dataset)
Number of Items: 1127 (a reduction of 72.39%)
Total Number of Interactions: 84,373 (a reduction of 12.30%)
