The main idea is to project the diffusion users into a continuous latent space as the role-based (sender and receiver) representations, which capture unique diffusion characteristics of users. The model learns the role-based representations based on a cascade modeling objective that aims at maximizing the likelihood of observed cascades, and employs the matrix factorization objective of reconstructing structural proximities as a regularization on representations. By jointly embedding the information of cascades and network, the learned representations are robust on different diffusion data. We evaluate the proposed model on three real-world datasets. The experimental results demonstrate the better performance of the proposed model than state-of-the-art diffusion embedding and network embedding models and other popular graph-based methods.<\/jats:p>","DOI":"10.1145\/3314106","type":"journal-article","created":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T14:11:11Z","timestamp":1557324671000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["Information Diffusion Prediction with Network Regularized Role-based User Representation Learning"],"prefix":"10.1145","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8552-3657","authenticated-orcid":false,"given":"Zhitao","family":"Wang","sequence":"first","affiliation":[{"name":"The Hong Kong Polytechnic University, Kowloon, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengyao","family":"Chen","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University, Kowloon, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjie","family":"Li","sequence":"additional","affiliation":[{"name":"The Hong Kong Polytechnic University, Kowloon, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2019,5,7]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1215842"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.18653\/v1\/P16-2003"},{"key":"e_1_2_1_3_1","volume-title":"Proceedings of the Advances in Neural Information Processing Systems. 2787--2795","author":"Bordes Antoine","year":"2013"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2556195.2556216"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/2835776.2835817"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2018.2807452"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/3132847.3132973"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2806416.2806512"},{"key":"e_1_2_1_9_1","volume-title":"Proceedings of the 16th International Conference on Artificial Intelligence and Statistics. 229--237","author":"Du Nan","year":"2013"},{"key":"e_1_2_1_10_1","volume-title":"Proceedings of the 13th International Conference on Artificial Intelligence and Statistics","volume":"9","author":"Glorot Xavier","year":"2010"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1011122126881"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1145\/1835804.1835933"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1145\/2433396.2433402"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/2939672.2939754"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1145\/2187980.2188254"},{"key":"e_1_2_1_16_1","volume-title":"Proceedings of the International Conference on Weblogs and Social Media.","author":"Hoang Tuan-Anh","year":"2012"},{"key":"e_1_2_1_17_1","volume-title":"Proceedings of the Association for the Advancement of Artificial Intelligence.","author":"Huo Zepeng","year":"2018"},{"key":"e_1_2_1_18_1","article-title":"Diffusion kernels on statistical manifolds","author":"Lafferty John","year":"2005","journal-title":"Journal of Machine Learning Research 6"},{"key":"e_1_2_1_19_1","doi-asserted-by":"publisher","DOI":"10.1145\/1557019.1557077"},{"key":"e_1_2_1_20_1","volume-title":"Proceedings of the Advances in Neural Information Processing Systems. 2177--2185","author":"Levy Omer","year":"2014"},{"key":"e_1_2_1_21_1","doi-asserted-by":"publisher","DOI":"10.1145\/3038912.3052643"},{"key":"e_1_2_1_22_1","volume-title":"Learning multi-faceted representations of individuals from heterogeneous evidence using neural networks.
