愛犯錯的智能體
會員

智能是什么?二十一世紀(jì)以來,人工智能有了飛速發(fā)展,在各行各業(yè)如互聯(lián)網(wǎng)、安防、多媒體等都有了廣泛且有效的應(yīng)用。但這是否意味著人類就能制造超越人類自身的智能體呢?作者在科普性地介紹了人工智能前沿進(jìn)展的同時(shí),著重從犯錯的角度,淺顯易懂地剖析了智能體在視、聽、語言等方面存在的各種錯覺和犯錯。并指出,理解我們很少關(guān)注的犯錯,才有利于智能體的研究和發(fā)展。書中從分析生物人的感知功能談起,以生動的例子介紹了人的視覺、聽覺、觸覺和體覺的解剖學(xué)知識及其基本原理。之后又進(jìn)入人的感情世界,從人的情感、回憶、夢境,一直談到靈感和錯覺。在這個(gè)過程中,作者又適時(shí)討論計(jì)算機(jī)在處理人的感知世界時(shí)會遇到的麻煩及處理原則,還不忘介紹一下討論對象的數(shù)學(xué)背景。高斯、黎曼、萊布尼茨、龐加萊、愛因斯坦、圖靈等大師級人物的名字頻頻出現(xiàn)。作者不費(fèi)力地游弋于生命、計(jì)算機(jī)、數(shù)學(xué)、物理等幾大學(xué)科之間,讓讀者經(jīng)歷一次目不暇接的跨學(xué)科科學(xué)旅游。再加上一個(gè)個(gè)有趣的故事,還有詩,畫,歌,甚至還有鄉(xiāng)愁!這樣的科普,很新鮮、很解惑,又易于接受。
