中國有工程師研發 AI 死者重生技術，給人們與死者最後說再見的機會

外媒報道，中國有工程師研發AI 死者重生技術，給人們與死者最後說再見的機會，利用已故死者的舊照片、錄音和聊天訊息，訓練 AI 聊天程序模仿死者，重建他們所愛的人。

The griefbot concept has been trialed for years — largely as AI-powered programs that learn how to mimic human beings through their memorabilia, photos, and recordings. But generative AI's rapid advancement in the last year has pushed the power and accessibility of griefbots to a whole new level.

Older models required vast sets of data. Now, laymen or lone engineers like Yu can feed language models with tidbits of a person's past, and recreate almost exactly how they look, speak, and think.

"In today's technology, you don't need too many samples for an AI to learn the style of a person," Haibing Lu, an information and analytics professor at Santa Clara University, told Insider.

Systems like ChatGPT, the popular text-based program that closely imitates human speech, have already learned how most people naturally speak or write, said Lu, whose research focuses on AI.

"You only need to tweak the systems a little bit in order to loosely get a 99% similarity to your person. The stark differences will be minimal," Lu said.

For Yu to teach his AI model what his grandfather was like, he retrieved a trove of old letters from his grandmother. She'd exchanged them with Yu's grandfather when they were young, and they revealed a side to the man that even Yu hadn't glimpsed as a child, he told Tang.

The software engineer dug up photos and videos shot more than a decade ago, and found text messages his grandfather sent him, Tang reported.

Yet even given weeks of testing and training, the tech has a long way to go if humans expect something akin to Black Mirror's robot replicas. Yu's bot was clearly limited, and took 10 minutes to respond to each prompt, Tang reported.

"Hey, Grandpa. Guess who I am?" Yu asked the program at one point.

Grandpa delivered a generic response.

"Who you are is not important at all. Life is a beautiful miracle," the bot wrote back, according to Tang.

But as Yu fed the AI with more information about his grandfather, it started to show a more accurate representation of the man's habits and preferences. For example, it remembered his grandfather's favorite show, he told Tang.

"Happy Teahouse went off the air," Yu told the chatbot.

"That's a shame. The show I want to watch the most is no longer available. I would have liked to watch a few more episodes," the grandfather bot replied.

That was the moment when Yu felt he'd gotten somewhere, he told Tang. The program was eventually sophisticated enough that Yu felt confident he could show his work to his grandmother. She watched silently as her late husband responded to her questions, then thanked her grandson, stood up, and left the room.

Yu told Tang his grandmother needed the chatbot to process her emotions and mourn. "Otherwise, why would she thank me?" he said.

As for himself, he declined to share his intimate conversations with his grandfather bot.

"But I think my grandfather forgave me in the end," he told Tang.

給人們與死者家屬最後說要錢的機會

Black Mirror

留番拜山先講

我很难受，叫医生来

概念又幾好

可以模仿死人 咁活人都可以
活人唔再愛我 就製造活人嘅AI
然後令活嘅消失
就可以得到佢唯一永恆嘅愛

抄black mirror當新idea

應該個墓上面張相改做LCD ，然後AI摸擬對話。

阿仔，今年燒咁少野比我？

毛主席訓斥維尼？

發死人財

每六秒六毫？

強國工程師? 我信佢一定做到， 假嘅就真

可唔可以裝落導航到
想聽希特拉幫我導航

大大做多五十届都得

馬上回來

死者AI: 下次拜山記得帶葡萄適俾禾

獨裁者可以永續統治？

It狗條橋？！
