We select User-ID = 46671 at random to demonstrate the proposed hybrid book recommender algorithm. The RMSE for the item-based model is 1.7670 and the MAE is 1.1331, whereas the RMSE for the ALS model is 2.0047 and the MAE is 1.6421. The item-based model performs slightly better than the ALS. The 5 books recommended by item-based model combined with the book popularity is shown in TABLE 1. The 5 books recommended by ALS model combined with book popularity is shown in TABLE 2.
