Modeling Information Diffusion with Sequential Interactive Hypergraphs

Hai Jin, Yao Wu, Hong Huang, Yu Song, Haohui Wei, Xuanhua Shi
2022 IEEE Transactions on Sustainable Computing  
On the one hand, Existing models only focus on the internal influence within the diffusion flow but ignore the external influence from the dissemination of other contents.  ...  To address these issues, we introduce the hypergraph structure and a sequential framework to model the complex interactions in social networks.  ...  Representation learning is widely used to learn the user embedding for further diffusion, such as EmbeddingIC [4], inf2Vec [5] and HID [7] .  ...

Sparsity-aware neural user behavior modeling in online interaction platforms [article]

Aravind Sankar
2022 arXiv   pre-print
Recently, representation learning has emerged as an effective strategy for user modeling, powered by neural networks trained over large volumes of interaction data.  ...  In this dissertation, we develop generalizable neural representation learning frameworks for user behavior modeling designed to address different sparsity challenges across applications.  ...  space of users. • Emb-IC [79] : an embedded cascade model that generalizes IC to learn user representations from partial orders of user activations. • Inf2vec [80] : an influence embedding method that  ...
