‘AI scientist’ brings us a step closer to the age of machine-generated scientific discovery | 24CA News

Humans are not the one ones able to making scientific discoveries. Kepler’s third regulation of planetary movement has been re-discovered centuries after it was first described – however this time, a man-made intelligence system is taking the credit score.

Dubbed AI-Descartes, this “AI scientist” was developed by a workforce of researchers from IBM Research, Samsung AI, and the University of Maryland, Baltimore County (UMBC).

“I think scientists have so many different problems to solve. And if we solve them faster with AI, they just open up brand new questions for us to go after next,” Tyler Josephson instructed Quirks & Quarks host Bob McDonald. 

Josephson co-authored a paper describing the brand new system, which was revealed this week within the educational journal Nature Communications.

“We are merging a first-principles approach, which has been used by scientists for centuries to derive new formulas from existing background theories, with a data-driven approach that is more common in the machine learning era,” Cristina Cornelio, a analysis scientist at Samsung AI who’s first writer on the paper, mentioned in a press launch.

While algorithms are excellent at discovering patterns in a sea of knowledge, most of them aren’t able to the very human job of seeing the massive image – combining these patterns with current scientific theories to make new discoveries. 

“What our system is doing is bringing logical reasoning into the mix – and it’s doing it in a very rigorous way,” defined Josephson, who’s an assistant professor of chemical, biochemical and environmental engineering at UMBC.

Similar to many AI algorithms, AI-Descartes can work with massive volumes of knowledge and generate equations that match that information in a course of referred to as symbolic regression.

But it has additionally been programmed with mathematical reasoning, which provides it the power to see how the reams of generated equations work with current background principle and determine which of them are helpful and legitimate.

Like scientists, AI-Descartes has to accumulate the background data first – with the assistance of its human analysis workforce. 

“We take theories that we know as humans, and we write them down in a way that the computer can understand,” Josephson defined.

“Then it will slot in each of these equations to fit data and then logically check, does this equation follow from the theory that we’ve given it?”

Through this course of, AI-Descartes has additionally been in a position to re-discover Einstein’s time dilation equation and Langmuir’s adsorption regulation, which governs the behaviour of gases. 

Researchers already work with AI algorithms to handle massive units of knowledge, and make correct predictions primarily based on real-world observations. The hope for AI-Descartes is that, finally, the bogus intelligence system will surpass its human lecturers.

“What our work is really thinking about is, could we use AI to discover new theories, not just applying our old theories in new contexts?” Josephson mentioned.
