Robust Causal Bandits for Linear Models

no code implementations30 Oct 2023 Zirui Yan, Arpan Mukherjee, Burak Varici, Ali Tajer

Cumulative regret is adopted as the design criteria, based on which the objective is to design a sequence of interventions that incur the smallest cumulative regret with respect to an oracle aware of the entire causal model and its fluctuations.

General Identifiability and Achievability for Causal Representation Learning

1 code implementation24 Oct 2023 Burak Varici, Emre Acartürk, Karthikeyan Shanmugam, Ali Tajer

For identifiability, the paper establishes that perfect recovery of the latent causal model and variables is guaranteed under uncoupled interventions.

Score-based Causal Representation Learning with Interventions

no code implementations19 Jan 2023 Burak Varici, Emre Acarturk, Karthikeyan Shanmugam, Abhishek Kumar, Ali Tajer

The objectives are: (i) recovering the unknown linear transformation (up to scaling) and (ii) determining the directed acyclic graph (DAG) underlying the latent variables.

Causal Bandits for Linear Structural Equation Models

1 code implementation26 Aug 2022 Burak Varici, Karthikeyan Shanmugam, Prasanna Sattigeri, Ali Tajer

Two linear mechanisms, one soft intervention and one observational, are assumed for each node, giving rise to $2^N$ possible interventions.

Thompson Sampling

Scalable Intervention Target Estimation in Linear Models

1 code implementation NeurIPS 2021 Burak Varici, Karthikeyan Shanmugam, Prasanna Sattigeri, Ali Tajer

This paper considers the problem of estimating the unknown intervention targets in a causal directed acyclic graph from observational and interventional data.
