Causal Discovery from Temporal Data: An Overview and New Perspectives

no code implementations17 Mar 2023 Chang Gong, Di Yao, Chuzhe Zhang, Wenbin Li, Jingping Bi

Existing causal discovery works can be divided into two highly correlated categories according to whether the temporal data is calibrated, ie, multivariate time series causal discovery, and event sequence causal discovery.

HTGN-BTW: Heterogeneous Temporal Graph Network with Bi-Time-Window Training Strategy for Temporal Link Prediction

no code implementations25 Feb 2022 Chongjian Yue, Lun Du, Qiang Fu, Wendong Bi, Hengyu Liu, Yu Gu, Di Yao

The Temporal Link Prediction task of WSDM Cup 2022 expects a single model that can work well on two kinds of temporal graphs simultaneously, which have quite different characteristics and data properties, to predict whether a link of a given type will occur between two given nodes within a given time span.

CausalMTA: Eliminating the User Confounding Bias for Causal Multi-touch Attribution

no code implementations21 Dec 2021 Di Yao, Chang Gong, Lei Zhang, Sheng Chen, Jingping Bi

Existing methods first train a model to predict the conversion probability of the advertisement journeys with historical data and calculate the attribution of each touchpoint using counterfactual predictions.
