Talk Abstract

Machine learning promises to revolutionize clinical decision making and diagnosis. It has long been known that causal reasoning is fundamental to how doctors perform diagnosis – doctors aim to explain a patient’s symptoms by determining the diseases causing them. However, existing data-driven machine learning approaches fail to differentiate correlation from causation. In this talk, we will explore how this failure to disentangle correlation from causation can lead to suboptimal or even dangerous diagnoses, and how these problems can be resolved by designing algorithms that can perform causal and counterfactual reasoning.
