Large-scale pre-trained language models (PLMs) are well-known for being capable of solving a task simply by conditioning a few input-label pairs dubbed demonstrations on a prompt without being explicitly tuned for the desired downstream task. Such a process (i.e., in-context learning), however, naturally leads to high reliance on the demonstrations which are usually selected from external datasets. In this paper, we propose self-generated in-context learning (SG-ICL), which generates demonstrations for in-context learning from PLM itself to minimize the reliance on the external demonstration. We conduct experiments on four different text classification tasks and show SG-ICL significantly outperforms zero-shot learning and is generally worth approximately 0.6 gold training samples. Moreover, our generated demonstrations show more consistent performance with low variance compared to randomly selected demonstrations from the training dataset.
PICARD: Parsing Incrementally for Constrained Auto-Regressive Decoding from Language Models

用于文本数据的大型预训练语言模型具有不受约束的输出空间;在每个解码步骤中,它们可以产生10,000个子单词标记中的任何一个。当对目标约束形式语言(如SQL)进行微调时,这些模型通常会生成无效代码,从而使其无法使用。我们提出了PICARD(code and trained models available at https://github.com/ElementAI/picard),这是一种通过增量解析来约束语言模型的自回归解码器的方法。PICARD通过在每个解码步骤中拒绝不可接受的令牌来帮助找到有效的输出序列。在具有挑战性的Spider和CoSQL文本到SQL的翻译任务中,我们展示了PICARD将性能尚可的微调T5模型转换为最先进的解决方案。
