Invariant Language Modeling

Maxime Peyrard, Sarvjeet Ghotra, Martin Josifoski, Vidhan Agarwal, Barun Patra, Dean Carignan +3

EMNLP 2022main

Modern pretrained language models are critical components of NLP pipelines. Yet, they suffer from spurious correlations, poor out-of-domain generalization, and biases.Inspired by recent progress in causal machine learning, in particular the invariant risk minimization (IRM) paradigm, we propose inva…

EPOpt: Learning Robust Neural Network Policies Using Model Ensembles

Aravind Rajeswaran, Sarvjeet Ghotra, Balaraman Ravindran, Sergey Levine

ICLR 2017poster

Sample complexity and safety are major challenges when learning policies with reinforcement learning for real-world tasks, especially when the policies are represented using rich function approximators like deep neural networks. Model-based methods where the real-world target domain is approximated…
