Matching User with Item Set:
Collaborative Bundle Recommendation with Deep Attention Network
Abstract
Most recommendation research has been concentrated on recommending single items to users, such
as the considerable work on collaborative filtering
that models the interaction between a user and an
item. However, in many real-world scenarios, the
platform needs to show users a set of items, e.g.,
the marketing strategy that offers multiple items for
sale as one bundle. In this work, we consider recommending a set of items to a user, i.e., the Bundle
Recommendation task, which concerns the interaction modeling between a user and a set of items. We
contribute a neural network solution named DAM,
short for Deep Attentive Multi-Task model, which
is featured with two special designs: 1) We design
a factorized attention network to aggregate the item
embeddings in a bundle to obtain the bundle’s representation; 2) We jointly model user-bundle interactions and user-item interactions in a multi-task
manner to alleviate the scarcity of user-bundle interactions. Extensive experiments on a real-world
dataset show that DAM outperforms the state-ofthe-art solution, verifying the effectiveness of our
attention design and multi-task learning in DAM
