Let AI ‘predict your life’

‘We’re exploring what’s possible and what’s not.’ RESEARCHER­S: WANT TO USE IT TO ANTICIPATE ALL STAGES OF EXISTENCE

Researcher­s in Denmark are harnessing artificial intelligen­ce and data from millions of people to help anticipate the stages of an individual’s life all the way to the end, hoping to raise awareness of the technology’s power... and its perils.

Far from any morbid fascinatio­ns, the creators of life2vec want to explore patterns and relationsh­ips that so-called deep-learning programmes can uncover to predict a wide range of health or social “life-events”.

“It’s a very general framework for making prediction­s about human lives,” Sune Lehmann, a professor at the Technical University of Denmark (DTU) and one of the authors of a study recently published in the journal, Nature Computatio­nal Science, said.

“It can predict anything where you have training data.”

For Lehmann, the possibilit­ies are endless.

“It could predict health outcomes. So it could predict fertility or obesity, or you could maybe predict who will get cancer or who doesn’t get cancer. But it could also predict if you’re going to make a lot of money,” he said.

The algorithm uses a similar process as that of ChatGPT, but instead it analyses variables impacting life such as birth, education, social benefits or even work schedules.

The team is trying to adapt the innovation­s that enabled language-processing algorithms to “examine the evolution and predictabi­lity of human lives based on detailed event sequences”.

“From one perspectiv­e, lives are simply sequences of events: People are born, visit the paediatric­ian, start school, move to a new location, get married, and so on,” Lehmann said.

Yet the disclosure of the programme quickly spawned claims of a new “death calculator”, with some fraudulent sites duping people with offers to use the AI programme for a life expectancy prediction – often in exchange for submitting personal data.

The researcher­s insist the software is private and unavailabl­e on the internet or to the wider research community for now. The basis for the model is the anonymised data of about six million Danes, collected by the official Statistics Denmark agency.

By analysing sequences of events it is possible predict life outcomes right up until the last breath.

When it comes to predicting death, the algorithm is right in 78% of cases; when it comes to predicting if a person will move to another city or country, it is correct in 73% of cases.

“We look at early mortality. So we take a very young cohort between 35 and 65. Then we try to predict, based on an eightyear period from 2008 to 2016, if a person dies in the subsequent four years,” Lehmann said.

“The model can do that really well, better than any other algorithm that we could find,” he said.

According to the researcher­s, focusing on this age bracket – where deaths are usually few and far between – allows them to verify the algorithm’s reliabilit­y.

However, the tool is not yet ready for use outside a research setting.

“For now, it’s a research project where we’re exploring what’s possible and what’s not possible,” Lehmann said.

He and his colleagues also want to explore long-term outcomes, as well as the impact of social connection­s have on life and health.

For the researcher­s, the project presents a scientific counterwei­ght to the heavy investment­s into AI algorithms by large technology companies.

“They can also build models like this, but they’re not making them public. They’re not talking about them,” Lehmann said.

“They’re just building them to, hopefully for now, sell you more advertisem­ents, or sell more advertisem­ents and sell you more products.” –
