9、算机程序来呈现人类智能的技术。器所表现出来的智能。通常人工智能是指通过普通计算机程序来呈现人类智能的技术。人工智能的定义可以分为两部分，即人工智能的定义可以分为两部分，即“人工人工”和和“智能智能”。“人工人工”比较好理解，争议性也不比较好理解，争议性也不大。有时我们会要考虑什么是人力所能及制造的，或者人自身的智能程度有没有高到可以创造大。有时我们会要考虑什么是人力所能及制造的，或者人自身的智能程度有没有高到可以创造人工智能的地步，等等。但总的来说，人工智能的地步，等等。但总的来说，“人工系统人工系统”就是通常意义下的人工系统。就是通常意义下的人工系统。11关于什么是关于什么是“智能智能”，就
10、问题多多了。这涉及到其它诸如意识（，就问题多多了。这涉及到其它诸如意识（CONSCIOUSNESSCONSCIOUSNESS）、自我）、自我（SELFSELF）、思维（）、思维（MINDMIND）（包括无意识的思维（）（包括无意识的思维（UNCONSCIOUS_MINDUNCONSCIOUS_MIND）等等问题。人唯一了解）等等问题。人唯一了解的智能是人本身的智能，这是普遍认同的观点。但是我们对我们自身智能的理解都非常有限，的智能是人本身的智能，这是普遍认同的观点。但是我们对我们自身智能的理解都非常有限，对构成人的智能的必要元素也了解有限，所以就很难定义什么是对构成人的智能的必要元素也了解有限
11、，所以就很难定义什么是“人工人工”制造的制造的“智能智能”了。了。因此人工智能的研究往往涉及对人的智能本身的研究。其它关于动物或其它人造系统的智能也因此人工智能的研究往往涉及对人的智能本身的研究。其它关于动物或其它人造系统的智能也普遍被认为是人工智能相关的研究课题。普遍被认为是人工智能相关的研究课题。20172017年年1212月，人工智能入选月，人工智能入选“2017“2017年度中国媒体十大流行语年度中国媒体十大流行语”。Artificial intelligence will be“either the best,or the worst thing ever to happen to
