CausalSmith: A Formally Grounded, Self-Improving Agentic Framework for Automated Research in Causal Inference

Jiyuan Tan, Vasilis Syrgkanis

Automating theoretical research is constrained not only by the generation of candidate results, but also by their reliable evaluation. A common approach is to close the research lo…

Mirror Descent on Riemannian Manifolds

Jiaxin Jiang, Lei Shi, Jiyuan Tan

Mirror Descent (MD) is a scalable first-order method widely used in large-scale optimization, with applications in image processing, policy optimization, and neural network trainin…

CausalReasoningBenchmark: A Real-World Benchmark for Disentangled Evaluation of Causal Identification and Estimation

Ayush Sawarni, Jiyuan Tan, Vasilis Syrgkanis

Many benchmarks for automated causal inference evaluate a system's performance based on a single numerical output, such as an Average Treatment Effect (ATE). This approach conflate…

Bucketing the Good Apples: A Method for Diagnosing and Improving Causal Abstraction

Li Puyin, Jiyuan Tan, Ahmad Jabbar +2

We present a method for diagnosing interpretation in neural networks by identifying an input subspace where a proposed interpretation is highly faithful. Our method is particularly…

Partial Identification of Policy-Relevant Treatment Effects with Instrumental Variables via Optimal Transport

Jiyuan Tan, Jose Blanchet, Vasilis Syrgkanis

Policy-Relevant Treatment Effects (PRTEs) are generally not point-identified under standard Instrumental Variable (IV) assumptions when the instrument generates limited support in…

Adaptive Estimation and Inference in Conditional Moment Models via the Discrepancy Principle

Jiyuan Tan, Vasilis Syrgkanis

We study adaptive estimation and inference in ill-posed linear inverse problems defined by conditional moment restrictions. Existing regularized estimators such as Regularized Deep…
