Equation 9 · Part 3 · How Edge AI Electronics and Sensor Systems Actually Work
Zero-point
What this part means
The integer code that stands for the real value zero. If Z = 10, then q = 10 decodes to r = 0 exactly. It shifts the integer code range left or right relative to real zero.
Its job in the formula
Z is one of the signed contributions combined to compute the quantity on the left.

The passage around this formula
The arithmetic-shrinking lever is quantization. A widely used scheme maps a real-valued weight or activation r onto a low-bit integer q through an affine relationship . with a scale S and a zero-point Z chosen so that ordinary 8-bit integers can represent the values a trained network actually produces. The 2018 paper that formalized this scheme for mobile and embedded inference showed that training the network with this quantization in the loop, rather than quantizing a finished floating-point…

The zero-point is the integer code chosen to mean the real value zero.
