About

Ruochi Zhang

I am a Phd student of Jilin Univerity. My reasearch area focuses on the data mining algorithms for the biomedical big data. Specifically, developing efficient feature selection, feature engineering and prediction algorithms for the high-dimensional biomedical data. At the same time, I am an entrepreneur. As the CAIO (chief artificial intelligence officer) of Beijing XDstar Technology Co., Ltd., I am responsible for the construction of the data platform and the development of data algorithms. I also works part-time as the data scientist and machine learning engineer in multiple companies, responsible for the implementation of AI products.

Patent

一种交易数据的异常检测方法、介质、装置和计算设备

  • 专利号:2019106169425
    本发明的实施方式提供了一种交易数据的异常检测方法、介质、装置和计算设备。该方法包括: 基于预先获得的交易数据生成知识图谱;知识图谱的节点用于表示交易数据中的账户实体,两个节点之间的边用于表示两个节点分别对应的账户实体之间的交易关系;利用图神经网络对知识图谱进行图深度学习,得到知识图谱中每条边的特征表示,并将边的特征表示确定为边对应的交易数据的特征向量;将预先确定的待检测交易数据的特征向量输入利用交易数据的特征向量训练得到的神经网络模型,经过神经网络模型的处理后,输出待检测交易数据的检测结果。

本发明能够自动化的完成交易数据的异常检测,与现有技术相比,避免了手动方式造成的不准确问题。
