月16日,《第一财经日报》记者获悉,百度今日在内部公布了Google Brain项目创始人
Andrew Ng(中文名吴恩达)加入百度的内部邮件。邮件显示,吴恩达出任百度首席科学
家职务,向百度高级副总裁王劲汇报。据了解,他将负责百度深度学习研究院工作,尤
其是Baidu Brain计划。

公开资料显示,吴恩达是斯坦福大学人工智能实验室主任,人工智能和机器学习领域国
际上最权威的学者之一。此前,吴恩达与谷歌合作研究深度学习,并领导谷歌X实验室
团队斥巨资打造的Google Brain项目,在谷歌内部推动深度学习算法,也被外界誉为“
Google Brain之父”。

此前, Google X实验室利用这一由16000多个处理器、10亿个内部节点组成的虚拟大脑
,分析了1000万帧从Youtube上随机抓取的无标签视频剪辑图片,经过了10天时间的运
转,“大脑”终于认识了什么是猫,并从接下来输入的2万张图片中准确找出了猫的照
片。

吴恩达同时还是在线教育平台Coursera的联合创始人。他在2008年发起“Stanford
Engineering Everywhere”(SEE)项目,这个项目把斯坦福的许多课程放到网上,供
免费学习,其中就包含Andrew Ng的课程,如机器学习等。

吴恩达的加盟与“百度大脑(Baidu Brain)”密切相关。2013年年初,百度成立深度
学习研究院IDL(Institute of Deep Learning),李彦宏亲自任院长一职,出马延揽硅
谷技术专家,如Facebook前资深科学家徐伟,美国新泽西州立大学统计学教授张潼,异
构计算专家、AMD异构系统前首席软件架构师吴韧,“千人计划”国家特聘专家余凯等
专家。

百度在美国硅谷设立的IDL,位于加利福尼亚州库比蒂诺附近,距离山景市的谷歌总部
仅6英里,在当地被称为“谷歌后花园”。


“百度大脑”计划被视为决定百度未来战略计划之一,通过用技术模拟人脑思维,百度
大脑现在大约已经相当于2~3岁孩子的智力水平。百度CEO李彦宏曾特别提及“百度大脑
(Baidu Brain)”融合深度学习算法、数据建模、大规模GPU并行化平台等技术,拥有
200亿个参数,构造起深度神经网络,将在政府、NGO、制造、金融、零售、教育等领域
开展项目合作。

目前深度学习在百度自身产品上已经开始应用。例如百度大脑已经可以理解语音、图像
、文本形式的检索请求,根据相关性做搜索排序;以及通过CTR(广告点击率)预估,做
广告的精准匹配。李彦宏预计,随着计算成本的飞速下降和计算能力的飞速提升,未来
十几二十年,这样的大脑或许比人脑还要聪明。”http://gengwg.blogspot.com/
