While we have witnessed spectacular advancements in Machine Learning over the past months and years, robustness of results and establishment of causal relations remain lacking. During this talk we will walk you through an example of using causal Machine Learning techniques to estimate causal, heterogeneous treatment effects with Open Source Python tooling. Learning causal relationships - in contrast to mere correlations - is of great importance for many applications where we'd like to learn how to intervene with the real world: To whom should we administer which medical drug? To whom should we offer a marketing voucher? For which automated processed should we make a human expert intervene? In such situations we'd like to rest assured our decision don't just rely correlations - potentially tainted by common confounders. Rather, we'd like to make causal statements about the heterogeneous effects of administering a treatment. In terms of making this happen, the field of Causal Inference has been able to incorporate progress from Machine Learning in theory. Yet, in practice, applications remain challenging: tooling is still somewhat immature and little examples to follow exist. Therefore, we would like to walk you through a case study of estimating causal, heterogeneous treatment effects with Open Source Python tooling. -------------------- About the speaker(s): Kevin is a Data Scientist at QuantCo, where he's been working with insurances on fraud detection, risk modelling and policy learning. In the past two years he's gotten into the field of Causal Inference. Prior to joining QuantCo, he majored in Computer Science at ETH in Zurich - focusing on Theoretical Computer Science and Machine Learning. He's passionate about Open Source and is the organizer of the PyData Zurich meetup. Francesc is a MSc Data Science student at ETH Zürich. Before that, he graduated in Maths & CS at the Polytechnic University of Catalonia (UPC) with a year abroad at Columbia University. He joined QuantCo as an intern in February 2024 to work on causal inference and its applications to insurance and fraud detection.
