The math we use to build an AI’s brain is exactly the same as the math that explains how the entire universe is held together.

The Takeaway
Researchers found that the way neural networks are initialized contains the same mathematical patterns found in string theory and exotic states of matter. This suggests that the architecture of modern AI is 'accidentally' encoding the deepest laws of physics.
From the abstract
Neural network field theory formulates field theory as a statistical ensemble of fields defined by a network architecture and a density on its parameters. We extend the construction to topological settings via the inclusion of discrete parameters that label the topological quantum number. We recover the Berezinskii--Kosterlitz--Thouless transition, including the spin-wave critical line and the proliferation of vortices at high temperatures. We also verify the T-duality of the bosonic string, sho
