UnverifiedGPTQ was proposed by Frantar et al. in 2022 and minimizes quantization error based on the inverse of the Hessian matrix; AWQ was proposed by Ji Lin et al. at MIT, with the core insight that a small number of weight channels associated with large activation values should retain higher precision.74% similarUnverifiedGPTQ was proposed in 2022 and extends the OBS framework from pruning to quantization, using the inverse of the Hessian matrix to optimally adjust unquantized weights to compensate for quantization error, with efficient updates via Cholesky decomposition.70% similarUnverifiedThe regret rates of the exponentiated weights algorithm and the algorithm of Tseng et al. (2025) are already optimal in their polynomial dependence on the dimension d, matching the lower bound.69% similarUnverifiedThe feasibility of the digital twin direction depends on improvements in the accuracy of computational chemistry methods such as density functional theory and molecular dynamics, as well as falling GPU cluster compute costs, and it is currently still limited by systematic deviations between simulation accuracy and real experiments.68% similarUnverified现代量化方法如 GPTQ、AWQ 通过逐层校准显著缓解了精度退化问题68% similar
