Quantization

Quantization is a technique used in machine learning and deep learning to reduce the precision of the numbers used in computations and storage. By converting floating-point values to lower bit-width representations, such as integers, quantization allows for more compact model sizes and improved computational efficiency. This process can significantly decrease memory bandwidth requirements and enhance the speed of model inference, particularly on hardware optimized for lower precision operations. PyTorch, for instance, supports INT8 quantization, which can lead to a fourfold reduction in model size and faster execution times compared to traditional FP32 models.
