As for Google, it uses AI to categorise content on YouTube, its online-video website, and weed out (some) objectionable material, and also to identify people and group them in its app, Google Photos. AI is also embedded in Android, its operating system, helping it to work more smoothly and to predict which apps people are interested in using. Google Brain is regarded in the field of AI as one of the best researchgroups at applying machine-learning advances profitably, for example by improving search algorithms. As for DeepMind, the British firm may not ever generate much actual revenue for Alphabet, but it has helped its parent save money by increasing the energy efficiency of its global data centres (and its Go experiment was a public-relations coup).
谷歌则利用AI为其在线视频网站 YouTube上的内容分组,并删除(一部分)不当内容,还利用AI在其应用“谷歌相册”中识别人物并分组。谷歌的安卓操作系统也嵌入了AI,帮助系统更加顺畅地运行,并预测人们有兴趣使用哪些应用。在AI领域,谷歌大脑团队(Google Brain)通过改进搜索算法等方法,利用机器学习的成果盈利,被认为是这方面最优秀的研究团队之一。而英国公司DeepMind也许从没有为Alphabet创造多少实际收入,但通过提高其全球数据中心的能效,帮助母公司节省了资金(而且它的围棋实验也是一次公关上的巨大胜利)。
