YOKOGAWA-NP53C

尼爾遜教授對人工智能下了這樣一個(gè)定義：“人工智能是關(guān)于知識的學(xué)科――怎樣表示知識以及怎樣獲得知識并使用知識的科學(xué)。”而另一個(gè)美國麻省理工學(xué)院的溫斯頓教授認(rèn)為：“人工智能就是研究如何使計(jì)算機(jī)去做過去只有人才能做的智能工作。”這些說法反映了人工智能學(xué)科的基本思想和基本內(nèi)容。即人工智能是研究人類智能活動(dòng)的規(guī)律，構(gòu)造具有一定智能的人工系統(tǒng)，研究如何讓計(jì)算機(jī)去完成以往需要人的智力才能勝任的工作，也就是研究如何應(yīng)用計(jì)算機(jī)的軟硬件來模擬人類某些智能行為的基本理論、方法和技術(shù)。

? ? 人工智能是計(jì)算機(jī)學(xué)科的一個(gè)分支，二十世紀(jì)七十年代以來被稱為世界三大尖端技術(shù)之一（空間技術(shù)、能源技術(shù)、人工智能）。也被認(rèn)為是二十一世紀(jì)三大尖端技術(shù)（基因工程、納米科學(xué)、人工智能）之一。這是因?yàn)榻陙硭@得了迅速的發(fā)展，在很多學(xué)科領(lǐng)域都獲得了廣泛應(yīng)用，并取得了豐碩的成果，人工智能已逐步成為一個(gè)獨(dú)立的分支，無論在理論和實(shí)踐上都已自成一個(gè)系統(tǒng)。

? ? 人工智能是研究使計(jì)算機(jī)來模擬人的某些思維過程和智能行為（如學(xué)習(xí)、推理、思考、規(guī)劃等）的學(xué)科，主要包括計(jì)算機(jī)實(shí)現(xiàn)智能的原理、制造類似于人腦智能的計(jì)算機(jī)，使計(jì)算機(jī)能實(shí)現(xiàn)更高層次的應(yīng)用。人工智能將涉及到計(jì)算機(jī)科學(xué)、心理學(xué)、哲學(xué)和語言學(xué)等學(xué)科?？梢哉f幾乎是自然科學(xué)和社會(huì)科學(xué)的所有學(xué)科，其范圍已遠(yuǎn)遠(yuǎn)超出了計(jì)算機(jī)科學(xué)的范疇，人工智能與思維科學(xué)的關(guān)系是實(shí)踐和理論的關(guān)系，人工智能是處于思維科學(xué)的技術(shù)應(yīng)用層次，是它的一個(gè)用分支。從思維觀點(diǎn)看，人工智能不僅限于邏輯思維，要考慮形象思維、靈感思維才能促進(jìn)人工智能的突破性的發(fā)展，數(shù)學(xué)常被認(rèn)為是多種學(xué)科的基礎(chǔ)科學(xué)，數(shù)學(xué)也進(jìn)入語言、思維領(lǐng)域，人工智能學(xué)科也必須借用數(shù)學(xué)工具，數(shù)學(xué)不僅在標(biāo)準(zhǔn)邏輯、模糊數(shù)學(xué)等范圍發(fā)揮作用，數(shù)學(xué)進(jìn)入人工智能學(xué)科，它們將互相促進(jìn)而更快地發(fā)展。
