Generalized Invariant Matching Property via LASSO

no code implementations14 Jan 2023 Kang Du, Yu Xiang

In this work, by formulating a high-dimensional problem with intrinsic sparsity, we generalize the invariant matching property for an important setting when only the target is intervened.

Learning Invariant Representations under General Interventions on the Response

no code implementations22 Aug 2022 Kang Du, Yu Xiang

One principled approach is to adopt the structural causal models to describe training and test models, following the invariance principle which says that the conditional distribution of the response given its predictors remains the same across environments.

An Invariant Matching Property for Distribution Generalization under Intervened Response

no code implementations18 May 2022 Kang Du, Yu Xiang

The task of distribution generalization concerns making reliable prediction of a response in unseen environments.

Causal Inference from Slowly Varying Nonstationary Processes

no code implementations23 Dec 2020 Kang Du, Yu Xiang

Causal inference from observational data following the restricted structural causal model (SCM) framework hinges largely on the asymmetry between cause and effect from the data generating mechanisms, such as non-Gaussianity or nonlinearity.
