2022-08-03 The publication "Temporal network epistemology: On reaching consensus in a real-world setting" previously published as an arXiv preprint has been accepted to Chaos: An Interdisciplinary Journal of Nonlinear Science and is available at https://doi.org/10.1063/5.0074992 (open access).
2022-08-02 In the work "CasSeqGCN: Combining network structure and temporal sequence to predict information cascades" recently published in Expert Systems with Applications we propose a CasSeqGCN model that combines information cascades embeddings and LSTMs to predict future cascades' size. The research on this topic has been conducted in collaboration with researchers from Southwest University (China) and is available at https://doi.org/10.1016/j.eswa.2022.117693 (open access).
