By Perri Thaler – Centaur is an AI model of human cognition that was trained on a curated dataset called Psych-101, which included data from 60,000 people who made more than 10 million individual choices over 160 psychology experiments, according to the paper. The researchers say it might be the world’s largest human behavior dataset.

“Essentially, we show the model a full transcript of a psychological experiment from a participant — everything they were told, have seen and have done,” study lead author Marcel Binz, a research scientist at the Helmholtz Institute for Human-Centered AI in Germany, told Live Science in an email.

The team then let the model predict what experiment participants chose in specific contexts. If the model predicted a choice that a person didn’t make in real life, the researchers would fine-tune the model by correcting its choice. They repeated this process over and over, until Centaur was regularly making correct predictions.

When tested against several established AI models of human thought, Centaur predicted behavior more accurately every time, according to the study. The model is unique because it can anticipate human choices in circumstances that it had never encountered during training, according to a statement from the Helmholtz Association of German Research Centres.

Notably, Centaur can also adapt to changing situations and predict human reaction times.  Read On:
