Causality is a fundamental concept in science that helps us understand the relationships between events or actions and their consequences. In recent years, machine learning has become increasingly important in understanding complex systems, but it often struggles to incorporate causal information. This survey article aims to bridge this gap by summarizing recent advances in causal machine learning.
Causal Machine Learning
Causal machine learning is a subfield of machine learning that focuses on developing algorithms and techniques for discovering cause-and-effect relationships from data. The article highlights several theoretical frameworks for approximate abstractions, including the work of Beckers et al., Rischel and Weichwald, and Zhu et al. These frameworks provide an explicit loss function that can be optimized efficiently and offer interpretable outcomes through a cause-mechanism decomposition.
Related Work
Several works have addressed desiderata for causal machine learning, including the context of continuous Bayesian networks (CBNs) and the notion of exact transformations. However, few works have focused on building high-level representations from low-level system data only. One line of works focuses on language models, where high-level variables and interpretations are readily available.
Contributions
The article provides a comprehensive overview of recent advances in causal machine learning, highlighting the need for developing algorithms that can handle complex systems with multiple mechanisms. The authors propose a novel approach based on approximate abstractions, which enables efficient optimization and offers interpretable outcomes. They also discuss related work in the field and identify future research directions.
