A Review of Causal Decision Making
It addresses the challenge of applying causal methods to decision-making in various domains, but it is incremental as it consolidates existing approaches rather than introducing new ones.
This review tackles the problem of integrating causal reasoning into decision-making by outlining a methodology that covers causal structure learning, effect learning, and policy learning, with a practical implementation framework provided in a Python-based collection.
To make effective decisions, it is important to have a thorough understanding of the causal relationships among actions, environments, and outcomes. This review aims to surface three crucial aspects of decision-making through a causal lens: 1) the discovery of causal relationships through causal structure learning, 2) understanding the impacts of these relationships through causal effect learning, and 3) applying the knowledge gained from the first two aspects to support decision making via causal policy learning. Moreover, we identify challenges that hinder the broader utilization of causal decision-making and discuss recent advances in overcoming these challenges. Finally, we provide future research directions to address these challenges and to further enhance the implementation of causal decision-making in practice, with real-world applications illustrated based on the proposed causal decision-making. We aim to offer a comprehensive methodology and practical implementation framework by consolidating various methods in this area into a Python-based collection.
