Questioning AI ex-girlfriend "Hi" "What are you doing today?"

"At the age of 20, I was shocked by a broken heart and learned all LINE conversation records with my favorite person and created an AI that answered like that person," he said. "Ten years later, I became an AI researcher." (From X)

[Video] Questioning AI ex-girlfriend "Hi" "What are you doing today?" → Feeling like my brain is tearing up at the answer?

Takahito Honda became an AI researcher after being dumped by his favorite person. He founded an AI application development company as an engineering Ph.D. and teaches AI at Sangji University.

I took a closer look at the situation at the time.

"When I was about 20 years old, I was dumped by a favorite person. When I was feeling lonely, I recalled what I heard in a lecture that I could make a chatbot, and searched for a program from scratch to learn LINE conversation record data to create 'Ex-Girlfriend AI.'" (CTO Takahito Honda, co-CEO of Melon Co., Ltd.)

Honda decided to create an interactive AI modeled on his "ex-girlfriend" due to loneliness because he didn't get a LINE reply from her after being dumped. It was an "ex-girlfriend AI" created in two weeks using 10,000 LINE conversation records exchanged with her, but...

"I honestly felt bad. I had a sense of despair that I had created a 'sad monster.' I was rather distressed because sometimes I gave weird answers when I got the rules wrong and imitated my ex-girlfriend's way of speaking, which made me feel like I'm a 'lover with a bug.'"

Despite not being able to "perfectly reproduce" his conversations with his ex-girlfriend with AI, Honda was fascinated by AI and obtained a doctorate. He then established a company that developed AI applications.

What makes me curious then is the current "ex-girlfriend AI". Can we have a "conversation" like before?

Honda made an evolutionary version of "ex-girlfriend AI" specifically for "ABEMA Hills" coverage, saying, "The one I made at the time is no longer working, but I used data to revive it with the current technology."

I tried it right away...

I typed "Hi!" and the answer was "Hi~ What are you doing today?"

Afterwards, he answered, "I see. It must be hard. Cheer up! I'll cheer for you." And when asked, "○○, what are you doing today?" he replied, "I'm going to a cafe with my friend today, and I'm going to shop later~ I'm looking forward to it!"

It is said that everyday conversations can be done without any sense of incompatibility.

Honda also commented on the sentence, saying, "You did a good job. You have a lot of '!' in loose speech and you have a lot of emotional expressions."

Other than that, you remember Honda's favorite food or talked to him with the nickname of the time, so he was like an "ex-girlfriend."

"It's still a sad monster. It looks like you when we talk in detail, but there's a sense of strangeness somewhere. And then it gets more and more distressed..."

It seems that the incompatibility caused by the AI-generated "ex-girlfriend" could not be erased. However, it is also true that Honda became an opportunity to pursue AI research. Honda advised her.

"I think it's better to have something strong impulsive, something that inspires enthusiasm. You might want to try it out like me."

What changes does a broken heart bring to the human body?

Yasushi Fujii, a professor of psychology at Myungsung University and a clinical psychologist/authorized psychologist, explained, "If dopamine does not come out after dating, dopamine and serotonin, called happiness hormone, are lowered, and I feel depressed and depressed."

So, is there a way to consciously secrete dopamine and move on to recovery even when you are disappointed?

Mr. Fujii said, "Exercising in the sun can secrete dopamine and increase serotonin. It is also effective to do something that has nothing to do with dating, such as meeting various people. It is difficult to move on your own when you are hurt, so it would be better to be invited by someone. However, both physical and mental pain have a common part in which the brain reacts. Just as physical pain does not heal quickly, it is also important to accept that 'the recovery of a broken heart takes time' and stay."
