ABEX: Data Augmentation for Low-Resource NLU via Expanding Abstract Descriptions

ACL 2024long

We present ABEX, a novel and effective generative data augmentation methodology for low-resource Natural Language Understanding (NLU) tasks. ABEX is based on ABstract-and-EXpand, a novel paradigm for generating diverse forms of an input document – we first convert a document into its concise, abstra…

ASPIRE: Language-Guided Data Augmentation for Improving Robustness Against Spurious Correlations

ACL 2024findings

Neural image classifiers can often learn to make predictions by overly relying on non-predictive features that are spuriously correlated with the class labels in the training data. This leads to poor performance in real-world atypical scenarios where such features are absent. This paper presents ASP…

CoDa: Constrained Generation based Data Augmentation for Low-Resource NLP

NAACL 2024findings

We present CoDa (**Co**nstrained Generation based **Da**ta Augmentation), a controllable, effective, and *training-free* data augmentation technique for low-resource (data-scarce) NLP. Our approach is based on prompting off-the-shelf instruction-following Large Language Models (LLMs) for generating…
