UniGen: Universal Domain Generalization for Sentiment Classification via Zero-shot Dataset Generation
Juhwan Choi, Yeong‐Hwa Kim, Seunguk Yu, Jungmin Yun, Youngbin Kim · 2024
Although pre-trained language models have exhibited great flexibility and versatility with prompt-based few-shot learning, they suffer from the extensive parameter size and limited applicability for inference.Recent studies have suggested that PLMs be used as dataset generators and a tiny task-specific model be trained to achieve efficient inference.However, their applicability to various domains is limited because they tend to generate domain-specific datasets.In this work, we propose a novel approach to universal domain generalization that generates a dataset regardless of the target domain.This allows for generalization of the tiny task model to any domain that shares the label space, thus enhancing the real-world applicability of the dataset generation paradigm.Our experiments indicate that the proposed method accomplishes generalizability across various domains while using a parameter set that is orders of magnitude smaller than PLMs.
