Adversarial Training for Commonsense Inference

Abstract

We propose an AdversariaL training algorithm for commonsense InferenCE (ALICE). We apply small perturbations to word embeddings and minimize the resultant adversarial risk to regularize the model. We exploit a novel combination of two different approaches to estimate these perturbations: 1) using the true label and 2) using the model prediction. Without relying on any human-crafted features, knowledge bases or additional datasets other than the target datasets, our model boosts the finetuning performance of RoBERTa, achieving competitive results on multiple reading comprehension datasets that require commonsense inference.
