Affine Quantization and Scale Quantization are range mapping techniques in Quantization (in ML). We have explored the difference between the two techniques (Affine Quantization vs

Scale: When quantizing a floating point range, one would typically represent a floating point range [Fmin..Fmax] in the quantized range [Qmin..Qmax]. In this case, the scale is the ratio of the floating point range and

Tensor Quantization: The Untold Story

Scale quantization performs range mapping with only a scale transformation. It is commonly referred to as symmetric quantization , where the input range and integer range are

We do not have per_tensor_symmetric tensor in the backend actually since per_tensor_symmetric can be represented by per_tensor_affine tensor, e.g. a

关于Scalar Quantization，网上资料比较多（梯子），但小白菜在查过很多资料后，发觉能把Scalar Quantization向量量化过程讲清楚，并且还能剖析faiss中实现的Scalar Quantization，几乎没有。为了方便后面的同学理解，小白菜结合自己

This does several things: # quantizes the weights, computes and stores the scale and bias value to be # used with each activation tensor, and replaces key operators with quantized #

Dynamic Quantization：仅量化权重，激活在推理时量化，无需校准数据; Static Quantization：权重和激活都量化，需要校准数据; Quantization Aware Training（QAT）量化

Scale and zero points are fundamental in the quantization process. The scale determines how much the original floating-point numbers are compressed. The zero point

Against a backdrop of increased research focus on why certain emergent properties surface at scale, this work provides a useful counter-example. We posit that it is

Per-tensor quantization: a single scale value (scalar) is used to scale the entire tensor. Per-channel quantization : a scale tensor is broadcast along the given axis – for convolutional neural networks, this is typically the

Quantization enables efficient acceleration of deep neural networks by reducing model memory footprint and exploiting low-cost integer math hardware units. Quantization

Quantization plays an important role in implementing energy-efﬁcient hardware for deep neural networks. Previ-ous work on quantization mostly considers uniform quan-tization, but non
