What is denoising-diffusion-implicit-models?
This is an educational implementation of a denoising diffusion model that utilizes a U-Net architecture for generating images. The model progressively processes images through a series of downsampling and upsampling operations, incorporating skip connections between layers of matching resolution. It's specifically designed to be computationally efficient while maintaining reasonable performance in natural image generation.
Implementation Details
The model architecture consists of convolutional residual blocks without attention layers, making it a simplified version of the DDPM architecture. It processes two inputs: noisy images and their noise component variances, which are encoded using sinusoidal embeddings. The training process involves 80 epochs with 5 dataset repetitions per epoch, using an AdamW optimizer with a learning rate of 1e-3 and weight decay of 1e-4.
