基于序列到序列的中文AMR解析(Chinese AMR Parsing based on Sequence-to-Sequence Modeling)

no code implementations CCL 2021 Ziyi Huang, Junhui Li, ZhengXian Gong

“抽象语义表示(Abstract Meaning Representation, 简称AMR)是将给定的文本的语义特征抽象成一个单根的有向无环图。AMR语义解析则是根据输入的文本获取对应的AMR图。相比于英文AMR, 中文AMR的研究起步较晚, 造成针对中文的AMR语义解析相关研究较少。本文针对公开的中文AMR语料库CAMR1. 0, 采用序列到序列的方法进行中文AMR语义解析的相关研究。具体地, 首先基于Transformer模型实现一个适用于中文的序列到序列AMR语义解析系统;然后, 探索并比较了不同预训练模型在中文AMR语义解析中的应用。基于该语料, 本文中文AMR语义解析方法最优性能达到了70. 29的Smatch F1值。本文是第一次在该数据集上报告实验结果。”

Push the Boundary of SAM: A Pseudo-label Correction Framework for Medical Segmentation

no code implementations2 Aug 2023 Ziyi Huang, Hongshan Liu, Haofeng Zhang, Xueshen Li, Haozhe Liu, Fuyong Xing, Andrew Laine, Elsa Angelini, Christine Hendon, Yu Gan

One key advantage of our model is its ability to train deep networks using SAM-generated pseudo labels without relying on a set of expert-level annotations while attaining good segmentation performance.

Unraveling the Mystery of Artifacts in Machine Generated Text

1 code implementation LREC 2022 Jiashu Pu, Ziyi Huang, Yadong Xi, Guandan Chen, WeiJie Chen, Rongsheng Zhang

As neural Text Generation Models (TGM) have become more and more capable of generating text indistinguishable from human-written ones, the misuse of text generation technologies can have serious ramifications.

Cardiac Adipose Tissue Segmentation via Image-Level Annotations

no code implementations9 Jun 2022 Ziyi Huang, Yu Gan, Theresa Lye, Yanchen Liu, Haofeng Zhang, Andrew Laine, Elsa Angelini, Christine Hendon

To lessen the need for pixel-wise labeling, we develop a two-stage deep learning framework for cardiac adipose tissue segmentation using image-level annotations on OCT images of human cardiac substrates.
