“…Label Hallucination (Jian and Torresani, 2022) assigns soft pseudo-labels for unlabelled images to extend the fine-tuning few-shot dataset. Learning from limited labeled data (few-shot learning) in Computer Vision is usually achieved by meta-learning (Ren et al, 2018a,b;Jian et al, 2020;Jian and Gao, 2021) or transfer learning (Tian et al, 2020). In NLP, few-shot learning has been successfully applied to machine translation (Arthaud et al, 2021), abstract summarizing (Fabbri et al, 2021), question and answering (Hua et al, 2020;Ram et al, 2021), and entity recognition (de Lichy et al, 2021;Tong et al, 2021;Ding et al, 2021), by meta learning (Li and Zhang, 2021;Bansal et al, 2020;Sharaf et al, 2020), data augmentation (Wei et al, 2021;Wei and Zou, 2019;Karimi et al, 2021;, and prompts Tam et al, 2021).…”
