Using AI to perceive the universe in greater depth

Researchers developed Deep Loop Shaping, an AI method using reinforcement learning to stabilize gravitational wave detectors at LIGO observatories. The technique reduces noise in the observatory's most unstable feedback loop by 30 to 100 times, allowing mirrors to remain still enough to measure distortions from cosmic events. Applying this across all of LIGO's mirror control systems could enable detection of hundreds more gravitational wave events annually, improving observations of intermediate-mass black holes and other cosmic phenomena.
