商品推荐系统

Overview

商品top50推荐系统

问题建模

本项目的数据集给出了15万左右的用户以及12万左右的商品, 以及对应的经过脱敏处理的用户特征和经过预处理的商品特征,旨在为用户推荐50个其可能购买的商品。

推荐系统架构方案

本项目采用传统的召回+排序的方案。在召回模块采用deepwalk, node2vec,item_feature, itemCF四种方法进行多路召回,为每位用户召回1000个商品。在排序阶段采用wide&deep模型,对召回的1000个商品进行排序。将排序所得的分数依据商品点击量进行后处理,来增大对非热门商品的曝光度。最后根据处理后的分数为每位用户推荐50个商品。

最终实现了在验证集上top50召回率0.807, 测试集上top50召回率0.712
