导读：计算机科学专业的人工智能方向分为几个分支？这些分支的大学排名情况如何？对于到美国读硕博的学生来讲，比较熟悉CSNews排名。今天我们从更加单一和直观的维度看看美国大学计算机科学的人工智能的五个分支方向各大学的实力。尽量少掺杂人为因素。产出比是一个不错的衡量指标，能看出某所大学的平均水平。
提起计算机科学，就让人想起卡内基梅隆大学，他确实是整体实力第一。对于想到美国的大学读硕博的同学来讲，我们关心的不只是整体实力，应该更加关注计算机科学下的每个分支的实力，这样才能让我们在选择学校和导师时与我们将来的发展规划更加契合和增加站在科技前沿的机会。
今天我们依据各个高校在计算机领域的顶级学术会议发表的论文数量，度量以下绝大多数院校教员在计算机科学领域的各大顶会所发布的论文数量。
这样能够帮助我们更精准的把握美国大学在计算机科学领域体系与师资方面的实力。每一篇论文都被精确地计算一次，最后通过计算所有作者的平均值来计算分数。数据所用的论文均来自 DBLP。
DBLP（DataBase systems and Logic Programming）是计算机领域内对研究的成果以作者为核心的一个计算机类英文文献的集成数据库系统。
计算机科学文献库DBLP Computer Science Bibliography在学术界有很好的声誉，给人们带来了极大的便利，其权威性也得到了研究界的高度认可。这个项目是德国特里尔大学的Michael Ley负责开发和维护。它提供计算机领域科学文献的搜索服务，但只储存这些文献的相关元数据，如标题，作者，发表日期等。
我们按照以下分类进行我们以下的话题。
分类原则如下：整体分为AI（人工智能）、Systems（计算机系统）、Theory（计算机原理）和Interdisciplinary Areas（交互区域）四个部分。
AI（人工智能）分为五个部分：
Artificial intelligence（人工智能）
Computer vision（计算机视觉）
Machine learning & data mining（机器学习和数据挖掘）
Natural language processing（自然语言处理）
The Web & information retrieval （网络和信息检索）
以下排名全部基于2008年至2018年间在国际会议发表的文章统计，不再每次都加以说明。
下图为整体排名，从整体排名看，卡内基梅隆大学是全球第一，教员人数也是第一的，说明卡内基梅隆大学确实汇集了一大批全球计算机科学方向的很多人才。
