Uncertainty-Aware Bootstrap Learning for Joint Extraction on Distantly-Supervised Data

1 code implementation5 May 2023 Yufei Li, Xiao Yu, Yanchi Liu, Haifeng Chen, Cong Liu

To mitigate such impact, we propose uncertainty-aware bootstrap learning, which is motivated by the intuition that the higher uncertainty of an instance, the more likely the model confidence is inconsistent with the ground truths.
