“专利文献是一种重要的技术文献, 是知识产权强国的重要工作内容。目前专利语料库多集中于信息检索、机器翻译以及文本文分类等领域, 尚缺乏更细粒度的标注, 不足以支持问答、阅读理解等新形态的人工智能技术研发。本文面向专利智能分析的需要, 提出了从解决问题、技术手段、效果三个角度对发明专利进行专利标注, 并最终构建了包含313篇的中文专利关键信息语料库。利用命名实体识别技术对语料库关键信息进行识别和验证, 表明专利关键信息的识别是不同于领域命名实体识别的更大粒度的信息抽取难题。”

Entropy Neural Estimation for Graph Contrastive Learning

1 code implementation • 26 Jul 2023 • Yixuan Ma, Xiaolin Zhang, Peng Zhang, Kun Zhan

In this paper, we theoretically illustrate that the entropy of a dataset can be approximated by maximizing the lower bound of the mutual information across different views of a graph, \ie, entropy is estimated by a neural network.
