Deepfake nghĩa là gì?

Deepfake = kết hợp của từ "deep learning" (học sâu) và "fake" (giả mạo) là kỹ thuật tổng hợp hình ảnh dựa trên trí thông minh nhân tạo, có thể tạo ra các video như thật mà trên thực tế không hề xảy ra, ví dụ các lãnh đạo thế giới hát mừng giáng sinh, hay thay mặt người nổi tiếng vào bất kỳ phim khiêu dâm nào v.v...

Ví dụ
Google actually provided some funding for this new research. So maybe these companies are keeping their cards close to their chest when it comes to deepfake detection (phát hiện). If you want to stay one step ahead of the fakers, that would certainly be a smart move.

This week the US House of Representatives intelligence committee asked Facebook, Twitter and Google what they were planning to do to combat (chiến đấu chống lại) deepfakes in the 2020 election (bầu cử). And it’s a fair question. With a bit of work, deepfakes could be convincing (thuyết phục) and misleading (gây lầm lẫn) enough to make fake news look like child’s play.

Image manipulation has been around for a long time, but AI is making sophisticated (tinh vi) fakery (giả mạo) more accessible. During an election, a deepfake could perhaps be used to be used to influence voters at the last moment. In May, a video of Nancy Pelosi that had been doctored (làm giả, giả mạo) to make it appear as if she were slurring (nói líu nhíu, nói lắp) her speech circulated rapidly on social media.

Have you ever wondered what would happen if you dropped Keanu Reeves and the cast of “Sesame Street” into a blender? Now you finally have the answer, thanks to a YouTube video that used deepfake trickery to edit Reeves’ face onto two singing children’s bodies. Deepfakes, or manipulated videos that make it look like people do or say things that never actually happened, could undermine trust in the media or threaten democracy (đe dọa dân chủ). But sometimes, like here, they lead to fun-albeit-creepy art projects.
