作者简介

Nikhil Buduma是Remedy的联合创始人和首席科学家，该公司位于美国旧金山，旨在建立数据驱动为主的健康管理新系统。16岁时，他在圣何塞州立大学管理过一个药物发现实验室，为资源受限的社区研发新颖而低成本的筛查方法。到了19岁，他是国际生物学奥林匹克竞赛的两枚金牌获得者。随后加入MIT，在那里他专注于开发大规模数据系统以影响健康服务、精神健康和医药研究。在MIT，他联合创立了Lean On Me，一家全国性的非营利组织，提供匿名短信热线在大学校园内实现有效的一对一支持，并运用数据来积极影响身心健康。如今，Nikhil通过他的风投基金Q Venture Partners投资硬科技和数据公司，还为Milwaukee Brewers篮球队管理一支数据分析团队。

本书内容贡献者Nick Locascio是一位深度学习顾问、作家和研究者。Nick在MIT的Regina Barzilay实验室获得了本科和工程硕士学位，专业从事NLP和计算机视觉研究。他曾工作于多个项目，从训练神经网络到编写自然语言提示，甚至与MGH Radiology部门合作将深度学习应用于乳腺X线摄影的医学辅助诊断。Nick的工作已被MIT News和CNBC报道。在其闲暇之余，Nick为财富500强企业提供私人的深度学习咨询服务。他还联合创立了标志性的MIT课程6.S191 Intro to Deep Learning，教过300余名学生，听众包括博士后和教授。
