Jointly Modeling Intra- and Inter-transaction Dependencies with Hierarchical Attentive Transaction Embeddings for Next-item Recommendation

  author={Shoujin Wang and Longbing Cao and Liang Hu and Shlomo Berkovsky and Xiaoshui Huang and Lin Xiao and Wenpeng Lu},
A transaction-based recommender system (TBRS) attempts to predict the next item by modeling dependencies in transactional data. Generally, two kinds of dependency considered are intra-transaction dependency and inter-transaction dependency. Most existing TBRSs recommend next item by only modeling the intra-transaction dependency within the current transaction while ignoring inter-transaction dependency with recent transactions that may also affect the next item. However, not all recent…

SASNet: Stage-aware Sequential Matching for Online Travel Recommendation

This paper proposes to capture the deep sequential context by modeling the evolving of user stages, and develops a novel stage-aware deep sequential matching network (SASNet) that incorporates inter-stage and intra-stage dependencies over stage-augmented interaction sequence for more accurate and interpretable recommendation.

Session-Based Recommendations for e-Commerce with Graph-Based Data Modeling

Two session-based recommendation methods for anonymous browsing in a generic e-commerce framework using a graph where items are connected to sessions and to each other based on the order of appearance or their co-occurrence, which compete favorably on a number of datasets.

Neural Cross-Session Filtering: Next-Item Prediction Under Intra- and Inter-Session Context

This work designs an efficient neural architecture to model both intra- and inter-context for next item prediction in session-based RSs, inspired by the successful experience in modern language modeling.

Interacting Attention-gated Recurrent Networks for Recommendation

The Interacting Attention-gated Recurrent Network (IARN) is presented which adopts the attention model to measure the relevance of each time step of user and item interaction history and can selectively memorize different time steps of a user's history when predicting her preferences over different items.

Diversifying Personalized Recommendation with User-session Context

It is argued that recommendation should be diversified by leveraging session contexts with personalized user profiles, and an efficient SBRS with shallow wide-in-wide-out networks is designed, inspired by the successful experience in modern language modelings.

Inferring Implicit Rules by Learning Explicit and Hidden Item Dependency

Experimental results show that IRRMiner not only infers implicit rules of various sizes consisting of both frequent and infrequent items effectively, it also runs at least four times faster than IARMiner, a typical indirect association rule mining algorithm which can only mine size-2 indirect association rules between frequent items.

Modeling Multi-Purpose Sessions for Next-Item Recommendations via Mixture-Channel Purpose Routing Networks

A mixture-channel model to accommodate the multi-purpose item subsets for more precisely representing a session and the superiority of MCPRN over the state-of-the-art methods in terms of both recommendation accuracy and diversity is shown.
