To discover new physics, AI may need to 'unlearn' the old one

- To discover new physics, AI may need to 'unlearn' the old one. A study in the Journal of Cosmology and Astroparticle Physics explores how transfer learning could dramatically reduce the computational cost of searching for new physics beyond the standard cosmological model—while also revealing an unexpected risk: Sometimes AI systems can become too reliant on what they already know. «Theoretically this could break physics or a market.»
