AI詩人挑戰人類作者，看圖作詩比賽機器人能否撥得頭籌？

05-20

太陽是美妙的事物

寂靜中被描畫

在林間

僅僅在光明的開端

"the sun is a beautiful thing

in silence is drawn

between the trees

only the beginning of light"

這首詩的作者是多愁善感的中學生還是人工智慧演算法？你能夠輕易的分辨出來嗎？

Was that poem written by an angsty middle schooler or an artificially intelligent algorithm? Is it easy to tell?

沒錯，你不能，我也不能，甚至是鑽研詩歌的專家學者也很難分辨。

Yeah, its not easy for us, either. Or for poetry experts, for that matter.

上周四，一篇發表於「arXiv」網站上的文章稱，一組來自微軟和東京大學的研究人員共同開發出了一款足以迷惑所有在線測試裁判的「AI詩人」。

A team of researchers from Microsoft and Kyoto University developed a poet AI good enough to fool online judges, according to a paper published Thursday on the preprint site arXiv.

使人工智慧自主創造，生成，逼真的人類語言。這簡直是人工智慧研發路上的又一壯舉！

Its the latest step towards artificial intelligence that can create believable, human-passing language, and, man, it seems like a big one.

為了達到這一步，研究人員通過給予人工智慧成千上萬的圖像以及與之匹配的描述和詩文，讓人工智慧在不斷的學習中建立圖像與文字的聯繫。

In order to generate something as esoteric as a poem, the AI was fed thousands of images paired with human-written descriptions and poems. This taught the algorithm associations between images and text.

同時，它還在過程中逐漸學會了意象，韻腳和語言的模式規律，以及特定顏色所關聯的情緒與隱喻。

It also learned the patterns of imagery, rhymes, and other language that might make up a believable poem, as well as how certain colors or images relate to emotions and metaphors.

當「AI詩人」訓練完成後，研究人員會隨機向它展示各種圖片，而它便根據圖片內容進行詩歌的創作。創作的作品不僅是需要關於圖片的，而且要讀起來像真正的詩歌，而不是演算法隨機的胡言亂語。

Once the AI was trained, it was then given an image and tasked with writing a poem that was not only relevant to the picture but also, you know, read like a poem instead of algorithmic nonsense.

然而事實上，有些作品確實相當無厘頭可笑，比如說：

And to be fair, some of the results were pretty nonsensical, even beyond the sorts of nonsense youd find in a college literary magazine.

這雨的國度

灰色的天穹與雲霧

悄然而平和

安全許可

this realm of rain

grey sky and cloud

its quite and peaceful

safe allowed

更荒謬的還有：

我是一輛拉煤車

因為一顆破碎的心

我無聲無息

我心之聲

我不是

（嗯…我不是，我沒有，別瞎說）

I am a coal-truck

by a broken heart

I have no sound

the sound of my heart

I am not

雖然在訓練過程中，不乏有以上一眼就能看出的機器殘次作品，但「AI詩人」如今的創作卻越來越出神入化了。

You could probably (we hope) pick those out of the crowd as machine-written. But while the AI is no Kendrick Lamar, many of the resulting poems actually did look like poems.

為了更加確信這一點，研究人員召集了一批在線測試裁判來參加對「AI詩人」的圖靈測試。

Next, the researchers had to see if the average person could tell the difference. That means: a Turing test of sorts.

根據不同的文學修養，裁判們被分為「普通裁判」和「專家裁判」。

The researchers found their judges on Amazon Mechanical Turk — an online service where people complete tasks that benefit from automation but still require human intelligence — and divided people up as either general users or "experts," who had some sort of background in literary academia.

裁判需要猜測每首詩歌的作者是人和還是AI，詩歌在展示給裁判時有時會附帶相應的圖片，而有時卻沒有。

These judges were then presented with poem after poem — sometimes with the associated picture, and sometimes without. They had to guess whether a human had written them, or whether AI had.

結果顯示，當作品附帶圖片時，專家裁判能更準確地辨認出機器作品；當作品沒有圖片時，普通裁判辨認機器作品的準確率更高。但是，兩組裁判都更擅長分辨人類的作品。

While the experts were better at identifying machine-written poems if they were given the image and general users were better without it, both groups were better at picking out the human-written poems than they were at identifying which ones were written by the new AI.

這就意味著，機器的作品已經具有相當強的欺騙性了。

That is to say, the machines had them fooled more often than not.

雖然擁有一桌的AI創作的詩集確實是一個美好的未來生活方式，但更大可能的是，此項AI語言生成技術將以更加商業化的方式，運用在廣告和客服聊天等領域。

While it might be neat to buy a coffee table book of robot poetry, odds are well see the convincing, evocative language that these algorithms have mastered in more commercially-relevant ways, like ads or customer service chatbots.

但即便如此，想像一個群未來充滿溫柔、有思想的機器人研究莎士比亞，並將他們破碎的心與運煤卡車進行比較，還是很不錯的。

But even so, its nice to imagine a future full of gentle, thoughtful robots studying Shakespeare and comparing their broken hearts to coal trucks.
