• Authors: Hang Chen, Keqing Du, Xinyu Yang, Chenguang Li
• Abstract summary: This paper divides the possible causal discovery tasks into three types according to the variable paradigm. We then define and instantiate the relevant datasets for each task and the final causal model constructed at the same time. We propose some roadmaps from different perspectives for the current research gaps in the field of causal discovery.

• Abstract: Understanding causality helps to structure interventions to achieve specific goals and enables predictions under interventions. With the growing importance of learning causal relationships, causal discovery tasks have transitioned from using traditional methods to infer potential causal structures from observational data to the field of pattern recognition involved in deep learning. The rapid accumulation of massive data promotes the emergence of causal search methods with brilliant scalability. Existing summaries of causal discovery methods mainly focus on traditional methods based on constraints, scores and FCMs, there is a lack of perfect sorting and elaboration for deep learning-based methods, also lacking some considers and exploration of causal discovery methods from the perspective of variable paradigms. Therefore, we divide the possible causal discovery tasks into three types according to the variable paradigm and give the definitions of the three tasks respectively, define and instantiate the relevant datasets for each task and the final causal model constructed at the same time, then reviews the main existing causal discovery methods for different tasks. Finally, we propose some roadmaps from different perspectives for the current research gaps in the field of causal discovery and point out future research directions.

• Detecting and Measuring Confounding Using Causal Mechanism Shifts [31.625339624279686]
  Causal sufficiency is both unrealistic and empirically untestable. Existing methods make strong parametric assumptions about the underlying causal generative process to guarantee the identifiability of confounding variables. We propose a comprehensive approach for detecting and measuring confounding.

  Causal Discovery is a technique that tackles the challenge by analyzing the statistical properties of the constituent variables. We question the current (possibly misleading) baseline results on the basis that they were obtained through supervised learning. In consequence, we approach this problem in an unsupervised way, using robust Mutual Information measures.
