4bit Quantized Training: Scaling Representation Range for Minimal Error
nrehiew_ · x · 2026-07-13
In 4bit quantized training, the next step is to scale the representation range to ±4 to reduce the maximum relative error. For activations and weights, two schemes are calculated respectively, and the one with the smallest representation error is selected. Due to high computational overhead, optimization through kernel tricks is required.
