Hejazi","Wenjing Zheng","Sathya Anand"],"abstract":"We present an end-to-end methodological framework for causal segment discovery that aims to uncover differential impacts of treatments across subgroups of users in large-scale digital experiments. Building on recent developments in causal inference and non/semi-parametric statistics, our approach unifies two objectives: (1) the discovery of user segments that stand to benefit from a candidate treatment based on subgroup-specific treatment effects, and (2) the evaluation of causal impacts of dynamically assigning units to a study's treatment arm based on their predicted segment-specific benefit or harm. Our proposal is model-agnostic, capable of incorporating state-of-the-art machine learning algorithms into the estimation procedure, and is applicable in randomized A/B tests and quasi-experiments. An open source R package implementation, sherlock, is introduced.","url_abs":"https://arxiv.org/abs/2111.01223v1","url_pdf":"https://arxiv.org/pdf/2111.01223v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"a-framework-for-causal-segmentation-analysis","repo_url":"https://github.com/netflix/sherlock","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"causal-inference","task_name":"Causal Inference"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
