吾不是學計算機或人工智能的,因此衹是也衹能從普通邏輯(即常識常理)去思考一下,但也正因為這樣才合適貼論壇。也希望了解計算機或人工智能的網友能解惑一二。
一,無窮多項問題
(之前寫的一個跟帖): In principle, can AI or any other software calculate the sum of a convergent infinite series? (Provided that the AI is indefinitely powerful).
For instance, the simple series 1 - 1/3 + 1/5 - 1/7 + ....... = pi /4
It doesn't matter how many terms are to be added up, the partial sum is always a rational number, but the sum (the limit) of the whole series is an irrational number (in fact, a so-called"transcendental number"). How can the AI decide on the irrationality of the sum? Since there are infinitely many terms, the speed of AI doesn't help.
If the general answer to this question is "No", then AI seems to have some serious intrinsic limitations.
二,任意長度問題
譬如,理論上,可以讓人工智能寫一首任意長度的詩(如一千萬行);無疑,這樣的作品是不成立的(不可能有真實的文學意義)。而這,不正説明了它寫的正常長度的詩(如二十行)本貭上也是不成立的?
周傑倫一些歌的歌詞就給我這個感覺,字麵(看似)文雅,實則無先無後,可不斷生成,長度任意。
