Specify Robust Causal Representation from Mixed Observations

1 code implementation21 Oct 2023 Mengyue Yang, Xinyu Cai, Furui Liu, Weinan Zhang, Jun Wang

Under the hypothesis that the intrinsic latent factors follow some casual generative models, we argue that by learning a causal representation, which is the minimal sufficient causes of the whole system, we can improve the robustness and generalization performance of machine learning models.
