面向产品推荐的对抗式学习

Adversarial learning for product recommendation

Joel R. Bock, Akhilesh Maewal

摘要:

产品推荐可以被认为是数据融合中的一个问题--估计个人、他们的行为以及感兴趣的商品或服务之间的联合分布。这项工作提出了一个有条件的,耦合的生成对抗网络(RecommenderGAN),学习从极其稀疏的隐式反馈训练数据中发现的(查看,购买)行为之间的联合分布中产生样本。用户交互由具有二进制值元素的两个矩阵表示。在每个矩阵中,非零值分别表示用户是否查看或购买了给定产品类别中的特定项目。通过以这种方式编码动作,模型能够表示整个大规模的产品目录。在训练的GAN输出样本上计算的转换率统计数据范围从1.323%到1.763%。与零假设检验结果相比,发现这些统计量是显著的。结果显示与许多行业和产品类型汇总的已公布转化率相当。我们的研究结果是初步的,但它们表明,该模型产生的建议可以为消费者和数字零售商提供实用性。

英文摘要:

Product recommendation can be considered as a problem in data fusion-- estimation of the joint distribution between individuals, their behaviors, and goods or services of interest. This work proposes a conditional, coupled generative adversarial network (RecommenderGAN) that learns to produce samples from a joint distribution between (view, buy) behaviors found in extremely sparse implicit feedback training data. User interaction is represented by two matrices having binary-valued elements. In each matrix, nonzero values indicate whether a user viewed or bought a specific item in a given product category, respectively. By encoding actions in this manner, the model is able to represent entire, large scale product catalogs. Conversion rate statistics computed on trained GAN output samples ranged from 1.323 to 1.763 percent. These statistics are found to be significant in comparison to null hypothesis testing results. The results are shown comparable to published conversion rates aggregated across many industries and product types. Our results are preliminary, however they suggest that the recommendations produced by the model may provide utility for consumers and digital retailers.
