Samsung patents method to shrink AI image generators for phones
Samsung describes a way to make diffusion models, which are used to generate images, smaller and faster. The method groups the steps the AI takes to create an image and adjusts the math in each group to use less memory without losing quality.
In the filing’s own words
A quantization method of a diffusion model comprises performing post-training quantization on a first diffusion model, to obtain a second diffusion model; dividing time steps of the second diffusion model into a plurality of time step groups; adjusting a weight of the second diffusion model for each of the plurality of time step groups, to obtain a third diffusion model; training the third diffusion model using an output of the first diffusion model, to adjust adjustment parameters of the third diffusion model, wherein the adjustment parameters of the third diffusion model reflect a change of a weight of the third diffusion model with respect to a weight of the second diffusion model; and quantizing the adjusted adjustment parameters of the third diffusion model to obtain a quantized diffusion model.
What exactly they claim (claim 1)
1. A quantization method of a diffusion model comprising: obtaining a second diffusion model by performing post-training quantization on a first diffusion model; dividing time steps of the second diffusion model into a plurality of time step groups; obtaining a third diffusion model by adjusting a weight of the second diffusion model for each time step group of the plurality of time step groups; adjusting adjustment parameters of the third diffusion model by training the third diffusion model using an output of the first diffusion model, wherein the adjustment parameters of the third diffusion model reflect a change of a weight of the third diffusion model relative to a weight of the second diffusion model; and obtaining a quantized diffusion model by quantizing the adjusted adjustment parameters of the third diffusion model.
