UnverifiedGradient descent updates parameters through the iterative formula θ = θ - α∇J(θ), where α is the learning rate and ∇J(θ) is the vector of partial derivatives of the loss function with respect to the parameters.65% similarUnverified4-bit quantization reduces model size to 1/8 of the original at the cost of approximately 1–3% accuracy loss.65% similarUnverifiedThe gradient descent update rule is v → v − η∇C; since η > 0 and ‖∇C‖² ≥ 0, each update is guaranteed to decrease the cost, ΔC ≤ 0.63% similarUnverified傅里叶衰减速率β与集合Hausdorff维数满足β ≤ dim_H，但等号不一定成立62% similarUnverifiedThe error introduced by uniform quantization approximately follows a uniform distribution, with a variance of Δ²/12 (where Δ is the quantization step size).62% similar
