除了統(tǒng)考模擬試題,今年機(jī)器人還挑戰(zhàn)了東京大學(xué)的數(shù)學(xué)模擬試題,但成績不及去年,標(biāo)分為55分左右,得到的評(píng)語是“擅長的領(lǐng)域偏少,需要克服不擅長的領(lǐng)域”。
“這個(gè)機(jī)器人就是通過學(xué)習(xí)以前的考試,通過神經(jīng)網(wǎng)絡(luò)算法,將以前的考試題目與試題之間建立種非線性聯(lián)系。當(dāng)需要考試的時(shí)候?qū)㈩}目作為這種非線性聯(lián)系的輸入,而輸出就是題目的答案!敝靽湔f。
據(jù)她介紹,其學(xué)習(xí)的過程就是不斷擴(kuò)充數(shù)據(jù)庫,數(shù)據(jù)庫越大,考試成績越,“不停地搜索數(shù)據(jù),也就是我們說的驗(yàn)學(xué)習(xí)”。
模擬人類形象思維方式
思維學(xué)普遍認(rèn)為,人類大腦的思維分為抽象(邏輯)思維、形象(直觀)思維和靈感(頓悟)思維三種基本方式!敖忸}機(jī)器人所依靠的網(wǎng)絡(luò)神經(jīng)算法就是模擬人思維的二種方式。”朱國卿說。
邏輯性的思維是指根據(jù)邏輯規(guī)則進(jìn)行推理的過程。它將信息轉(zhuǎn)化成概念,并用符號(hào)表示,然后,根據(jù)符號(hào)運(yùn)算按串行模式進(jìn)行邏輯推理。這過程可以寫成串行的指令,讓計(jì)算機(jī)執(zhí)行。而直觀性的思維是將分布式存儲(chǔ)的信息綜合起來,結(jié)果是忽然間產(chǎn)生想法或解決問題的辦法。
“要想使這個(gè)解題機(jī)器人真正具有學(xué)習(xí)的能力,關(guān)鍵的就是建造個(gè)人工神經(jīng)網(wǎng)絡(luò)。”朱國卿說。
人工神經(jīng)網(wǎng)絡(luò)是由大量簡單的基本元件—神經(jīng)元相互聯(lián)接而成的自適應(yīng)非線性動(dòng)態(tài)系統(tǒng)。每個(gè)神經(jīng)元的結(jié)構(gòu)和功能比較簡單,但大量神經(jīng)元組合產(chǎn)生的系統(tǒng)行為卻非常復(fù)雜。
