一名在優步工作的軟體工程師創建了一個網站，展示人工智慧創造假臉能力的進步。上圖中的人都不是真實的。（此人不存在網站）

Fake news may soon be supplanted by AI-generated fake visuals, which probably isn"t good for digital literacy.

虛假新聞可能很快就會被人工智慧生成的虛假圖像所取代，這可能不利於數字素養。

A new website, ThisPersonDoesNotExist.com, demonstrates the technology"s power by using research to create an endless stream of fake portraits when you refresh the page.

一個名為「此人不存在」的新網站展示了這項技術的威力，它通過研究，在你刷新頁面時創建了無數張假肖像。

According to The Verge, the algorithm behind the site is trained on a huge dataset of real images, but then uses a type of neural network known as a generative adversarial network (GAN) to produce the fakes.

據The Verge網站介紹，該網站背後的演算法是在一個巨大的真實圖像數據集上進行訓練，然後使用一種被稱為生成對抗網路的神經網路生成假圖像。

"Each time you refresh the site, the network will generate a new facial image from scratch," Philip Wang, a software engineer from Uber who built the site, wrote on Facebook.

「每次你一刷新網站，該網就會從頭開始生成一個新的面部圖像。」創建該網站的優步軟體工程師菲利普?王在Facebook上寫道。

The technology underlying the site was reportedly first invented by Ian Goodfellow. This version of the model was trained on human faces, but researchers are also experimenting with anime characters, fonts and graffiti.

據報道，該網站隱含的技術首先是由伊恩?古德費羅發明的。這個模型的版本是在人臉上進行訓練的，但研究人員也在用動畫人物、字體和塗鴉進行試驗。

Artificial intelligence-generated imagery — which does have positive uses for designers — can also be harnessed for deepfakes, in which peoples" faces are pasted onto other photographs (sometimes pornography) without their consent.

人工智慧生成的圖像對設計者確實有積極的用途，還可以用於換臉技術，即未經允許將人們的臉粘到其他照片（有時是色情照片）上。

In addition, the technology can be used to create political propaganda or influence campaigns, according to experts.

此外，專家表示，這項技術還可以用來進行政治宣傳或影響競選活動。
