Repeat Consumption Recommendation Based on Users Preference Dynamics and Side Information

Dimitrios Rafailidis, Alexandros Nanopoulos
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
Repeat consumption recommendations are generated based on factorizing the coupled tensor, by weighting the importance of past user preferences according to the captured rate.  ...  We present a Coupled Tensor Factorization model to recommend items with repeat consumption over time.  ...  consequently the model cannot identify any other user to base the recommendation according to the side information of the d-th attribute.  ...

Sanggil Kang, Sungjoon Park
2007 Lecture Notes in Computer Science  
We also implemented our system based on Java Micro Edition platform.  ...  From the binary decision tree, we identify the preference clones of each target user by matching the target user's consumption behavior to that of each sub-group in the BDT with a sequential manner.  ...  Then, it recommends preferred contents to each target user. The client side has one module called Information Manager Module (IMM). The IMM displays recommendation list provided from the server side.  ...

Learning from History and Present

Zhi Li, Hongke Zhao, Qi Liu, Zhenya Huang, Tao Mei, Enhong Chen
2018 Proceedings of the 24th ACM SIGKDD International Conference on Knowledge Discovery & Data Mining - KDD '18  
In the modern e-commerce, the behaviors of customers contain rich information, e.g., consumption habits, the dynamics of preferences.  ...  In this paper, we propose a novel Behavior-Intensive Neural Network (BINN) for next-item recommendation by incorporating both users' historical stable preferences and present consumption motivations.  ...  The dynamics and evolutions of users' preferences, and also their present consumption motivations are usually not given special attentions.  ...

2017 Proceedings of the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '17  
On one hand, user generated lists contain rich signal about item co-occurrence, as items within a list are usually gathered based on a speci c theme.  ...  Speci cally, we employ factorization model to capture users' preferences over items and lists, and utilize embeddingbased models to discover the co-occurrence information among items and lists. e gap between  ...  It weights items within lists based on both position of items and personalized list consumption pa ern.  ...

2020 arXiv   pre-print
To achieve both adaptive weights assignment and efficient model learning, we propose a fast adaptively weighted matrix factorization (FAWMF) based on variational auto-encoder.  ...  Further, to support fast and stable learning of FAWMF, a new specific batch-based learning algorithm fBGD has been developed, which trains on all feedback data but its complexity is linear to the number  ...  Here we do not compare with existing dynamic sampling strategies, since they either suffer from efficiency problems or require other side information.  ...
