Structural Causal Bandits: Where to Intervene?

Sanghack Lee, Elias Bareinboim
2018 Neural Information Processing Systems  
We leverage this characterization to build a new algorithm that takes as input a causal structure and finds a minimal, sound, and complete set of qualified arms that an agent should play to maximize its  ...  For example, a linear (or combinatorial) bandit imposes that an action x t 2 R d (or {0, 1} d ) at a time step t incurs a cost '> t x t , where 't is a loss vector chosen by, e.g., an adversary.  ...  (We note that the causal structure can easily be learned in a typical MAB setting since the agent always has interventional capabilities.)  ...

Structure induction in diagnostic causal reasoning

Björn Meder, Ralf Mayrhofer, Michael R. Waldmann
2014 Psychological review  
Our structure induction model of diagnostic reasoning takes into account the uncertainty regarding the underlying causal structure.  ...  We argue against this assumption, as it neglects alternative causal structures that may have generated the sample data.  ...  This account is based on the idea that causal learning and inference are guided by general systematic assumptions about the structure of the (causal) environment, which entails a preference for fewer (  ...

Quantifying intrinsic causal contributions via structure preserving interventions [article]

Dominik Janzing, Patrick Blöbaum, Lenon Minorics, Philipp Faller, Atalanti Mastakouri
2021 arXiv   pre-print
To interpret the intrinsic information as a causal contribution, we consider 'structure-preserving interventions' that randomize each node in a way that mimics the usual dependence on the parents and do  ...  We propose a new notion of causal contribution which describes the 'intrinsic' part of the contribution of a node on a target node in a DAG.  ...  How To Learn The Structural Equations Since the FCM does not uniquely follow from the observed causal conditional P Xj |P Aj , it is natural to ask where it comes from.  ...

Raj Agrawal, Chandler Squires, Karren Yang, Karthik Shanmugam, Caroline Uhler
2019 arXiv   pre-print
Determining the causal structure of a set of variables is critical for both scientific inquiry and decision-making. However, this is often challenging in practice due to limited interventional data.  ...  That is, we assume the experimenter is interested in learning some function of the unknown graph (e.g., all descendants of a target node) subject to design constraints such as limits on the number of samples  ...  Uhler was partially supported by NSF (DMS-1651995), ONR (N00014-17-1-2147 and N00014-18-1-2765), IBM, and a Sloan Fellowship.  ...
