TorchLean: Formalizing Neural Networks in Lean
Researchers have developed TorchLean, a framework that formalizes neural networks within the Lean 4 theorem prover. This system allows for the execution and verification of neural networks directly within the same environment where mathematical proofs are conducted. TorchLean supports various neural network components, including attention mechanisms and diffusion models, and offers features for exact and finite-precision tensor semantics, differentiation, and bound propagation.
