Fake news may soon be supplanted by AI-generated fake visuals, which probably isn't good for digital literacy.

虚假新闻可能很快就会被人工智能生成的虚假图像所取代，这可能不利于数字素养。

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.

一个名为“此人不存在”的新网站展示了这项技术的威力，它通过研究，在你刷新页面时创建了无数张假肖像。

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.

据The Verge网站介绍，该网站背后的算法是在一个巨大的真实图像数据集上进行训练，然后使用一种被称为生成对抗网络的神经网络生成假图像。

"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.

“每次你一刷新网站，该网就会从头开始生成一个新的面部图像。”创建该网站的优步软件工程师菲利普•王在Facebook上写道。

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.

据报道，该网站隐含的技术首先是由伊恩•古德费罗发明的。这个模型的版本是在人脸上进行训练的，但研究人员也在用动画人物、字体和涂鸦进行试验。

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.

人工智能生成的图像对设计者确实有积极的用途，还可以用于换脸技术，即未经允许将人们的脸粘到其他照片（有时是色情照片）上。

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

此外，专家表示，这项技术还可以用来进行政治宣传或影响竞选活动。
