Stored integer code
What this part means
The whole-number code kept in the compact representation. For example, q = 14 is a code; it is not itself the model value 14. The allowed code range depends on the chosen integer format.
Its job in the formula
q is one of the signed contributions combined to compute the quantity on the left.
The passage around this formula
…using integer arithmetic end to end. The scheme that made this practical for commodity hardware is an affine mapping between a real value and its stored integer, . where r is the real-valued number, q is the stored integer, S > 0 is a scale factor, and Z is an integer zero-point chosen so that real zero maps exactly onto a representable integer — a detail that matters because operations like zero-padding and ReLU depend on zero being represented without rounding error. Jacob and colleagues…
Learn the underlying idea
Quantization maps many possible numerical values onto a smaller set of codes. It helps a small device store and process a neural network using compact integer arithmetic.
