AI 在方方面面改变着很多公司的业务处理方式。不过在对有价值数据的处理和智能化方面，却有所区别。随着对效率和精确性的要求不断增加，一流 AI 和数据科学家的缺口也越来越大。

在 PayPal，借助领先的 AI、现代化的数据基础设施、巨大无比的数据以及科学家的聪明才智，我们使全球支付业务发生了革命性变化，并使金融服务大众化。

作为 PayPal 全球风险管理建模团队的资深总监，王辉在本次演讲中将和大家一起探讨 PayPal 卓越的数据科学团队是如何构建内部 AI 系统，并使 PayPal 将损失率（loss rate）控制在 0.29% 的（业界最低的损失率之一）。

AI is changing the way companies do business in almost every way. But what companies do with the valuable data and intelligence is what makes the difference. With increasing demand for efficiency and accuracy comes a growing demand for stellar AI and data scientists. At PayPal, with the combination of advanced AI, modern data infrastructure, humongous amount of data, and brilliant minds from our scientists, we are revolutionizing global payments and democratizing financial services.  Join Hui Wang, Sr. Director of Global Risk and Data Sciences, as she discusses how PayPal’s unique data science teams have built their own in-house AI systems and given PayPal one of the lowest loss rates in the industry at .29 percent.
