DNA-reading AI reconstructs ancestry in minutes, matching top statistical methods

Phys · · 910 words · By Leila Okahata

Researchers at the University of Oregon have developed an AI tool based on a modified GPT-2 architecture to reconstruct evolutionary history and ancestry from genetic mutations. The tool matches the accuracy of traditional statistical methods while significantly reducing the time required to process large or incomplete genomic datasets.
