TART: Improved Few-shot Text Classification Using Task-Adaptive Reference Transformation

ACL 2023long

Meta-learning has emerged as a trending technique to tackle few-shot text classification and achieve state-of-the-art performance. However, the performance of existing approaches heavily depends on the inter-class variance of the support set. As a result, it can perform well on tasks when the semant…

Cross-Domain Few-Shot Semantic Segmentation

ECCV 2022poster

"Few-shot semantic segmentation aims at learning to segment a novel object class with only a few annotated examples. Most existing methods consider a setting where base classes are sampled from the same domain as the novel classes. However, in many applications, collecting sufficient training data f…

Uncertainty-Aware Cross-Lingual Transfer with Pseudo Partial Labels

NAACL 2022findings

Large-scale multilingual pre-trained language models have achieved remarkable performance in zero-shot cross-lingual tasks. A recent study has demonstrated the effectiveness of self-learning-based approach on cross-lingual transfer, where only unlabeled data of target languages are required, without…
