2015 arXiv   pre-print
With real-world user action data provided by Tmall, one of the largest B2C online retail platforms in China, this competition requires to predict future user purchases on Tmall website.  ...  We model the purchase prediction problem as standard machine learning problem, and mainly employ regression and classification methods as single models.  ...  In training, we use the last month as the target span and previous months as the feature span. In predicting, we use all available months as the feature span.  ...

Improving Implicit Recommender Systems with View Data

Jingtao Ding, Guanghui Yu, Xiangnan He, Yuhan Quan, Yong Li, Tat-Seng Chua, Depeng Jin, Jiajie Yu
2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
Most existing recommender systems leverage the primary feedback data only, such as the purchase records in E-commerce.  ...  We propose to model the pairwise ranking relations among purchased, viewed, and non-viewed interactions, being more effective and flexible than typical pointwise matrix factorization (MF) methods.  ...  For a specific user u, vector p u ∈ R K denotes the K-dimensional latent feature vector, and set R u denotes the set of items that are interacted by u.  ...

Learning Recommender Systems from Multi-Behavior Data [article]

Chen Gao, Xiangnan He, Dahua Gan, Xiangning Chen, Fuli Feng, Yong Li, Tat-Seng Chua, Depeng Jin
2018 arXiv   pre-print
Further analysis shows that modeling multiple behaviors is particularly useful for providing recommendation for sparse users that have very few interactions.  ...  In particular, our model accounts for the cascading relationship among different types of behaviors (e.g., a user must click on a product before purchasing it).  ...  Specifically, the performance of (Purchase, 50% Carting) is worse than only using purchase, while (Purchase, 50% Viewing) is better than only using purchase. There are two major reasons.  ...

Interest-Behaviour Multiplicative Network for Resource-limited Recommendation [article]

Qianliang Wu and Tong Zhang and Zhen Cui and Jian Yang
2020 arXiv   pre-print
Finally, mutual information is introduced to measure the similarity between the user action and fused features to predict future interaction, where the fused features come from both MRRNNs and resource-limited  ...  We test the performance on the built used car transaction dataset as well as the Tmall dataset, and the experimental results verify the effectiveness of our framework.  ...  We treat purchase actions as 'purchase' interactions while the other two kinds of actions as 'click'. We obtain the image feature using vgg16 features while the structure feature using id embedding.  ...

Cascading Residual Graph Convolutional Network for Multi-Behavior Recommendation [article]

Mingshi Yan, Zhiyong Cheng, Chen Gao, Jing Sun, Fan Liu, Fuming Sun, Haojie Li
2022 arXiv   pre-print
Most existing multi-behavior recommendation methods take the strategy to first extract information from different behaviors separately and then fuse them for final prediction.  ...  Specifically, the next behavior provides more specific information which can help us refine user's preference.  ...  On The Tmall platform, users can buy the item directly after page viewing, or add it to the cart before purchasing, or they may just click on the collection instead of the purchase behavior. • Beibei.  ...

Non-Compensatory Psychological Models for Recommender Systems

Chen Lin, Xiaolin Shen, Si Chen, Muhua Zhu, Yanghua Xiao
We show how this conceptual model can be realized in both pointwise rating prediction models and pair-wise ranking prediction models.  ...  models which are based on latent factor models assume the consumers follow the compensatory rules, i.e. they evaluate an item over multiple aspects and compute a weighted or/and summated score which is used  ...  Tmall-hybrid: the pairwise rankings are built by extracting purchased items in each session and all remaining items which are not purchased in the same session.  ...
