It is shown that the more reliable items are recommended, the more relevant the recommendations will be to the user's preferences [19,[65][66][67]. Therefore, considering the reliability of predictions in RSs can significantly improve the accuracy of recommendations, which results in increasing user's satisfaction. ...
