Compared with published cryptanalysis results, the proposedattack has obvious advantages.
4913	现有的推荐模型大多仅从用户角度进行建模，忽略了物品的功能关系对用户购买决策的影响。	Most of existing recommendation models constructed pairwise samples only from a user's perspective. Never-theless, they overlooked the functional relationships among items--A key factor that could significantly influence userpurchase decision-making process.
