WebFor symmetric quantization, the zero point is initialized to 0, and kept fixed. For asymmetric quantization, zero point is initialized to \(N_{min}\) if the activation is non-negative. Inspired by LSQ plus, the zero point can also be updated through backpropagation with the help of STE. Therefore we make it learnable in asymmetric quantization. WebLM quantization scheme, by analyzing the biases and variances of estimators in the symmetric case. That is, the observations x iand y iare quantized by the same LM scheme with the same number of bits (b). In this paper, we study the asymmetric setting by using b 1 number of bits for quantizing x iand b 2 number of bits for y i.

This is for the … WebSymmetric quantization is a simplified version of the general asymmetric case. The symmetric quantizer restricts the zero-point to 0. This reduces the computational overhead of dealing with zero-point offset during the accumulation operation in equation (3). But the lack of offset restricts the mapping between integer and floating-point domain. sho pen
