Offset from zero
What this part means
Count how many integer steps q lies above or below the zero-point. A positive result gives a positive model value; a negative result gives a negative one.

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 model after the fact, preserves accuracy far better, and that integer-only arithmetic — no floating-point unit required anywhere in the inference path — can be implemented…

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