Quantisation

Representing model parameters with lower-precision numerical formats.

Quantisation reduces the precision used to store weights and perform calculations. A model trained with 32-bit floating-point numbers may be converted to 16-bit, 8-bit or lower-precision formats.

This reduces memory use, power consumption and inference latency. Excessive quantisation can reduce accuracy, so calibration and quantisation-aware training may be required.
