Fast radio bursts are millisecond-long cosmic signals. Previously, searching for them was like blindly tuning a radio dial. The EDEN neural network sees the entire frequency spread and recognizes the burst pattern like a musician reads notes. On source FRB 20121102A, it found 5,927 bursts — three times more than before.

Fast radio bursts — millisecond radio pulses arriving from distant galaxies — long remained a puzzle. Their colossal energy, compressed into instants, pointed to cataclysms on neutron stars, perhaps pulsars or magnetars.
