The Lattice Geometry of Neural Network Quantization -- A Short Equivalence Proof of GPTQ and Babai's Algorithm

Researchers prove that the GPTQ neural network quantization algorithm is mathematically equivalent to Babai's nearest-plane algorithm for solving lattice problems. The work establishes a connection between neural network quantization and lattice geometry, suggesting potential improvements through lattice basis reduction techniques.

Provable Post-Training Quantization: Theoretical Analysis of OPTQ and Qronos

Researchers provide the first rigorous theoretical analysis of OPTQ (GPTQ), a widely-used post-training quantization algorithm for neural networks and LLMs, establishing quantitative error bounds and validating practical design choices. The study extends theoretical guarantees to both deterministic and stochastic variants of OPTQ and the Qronos algorithm, offering guidance for regularization parameter selection and quantization alphabet sizing.
