💥 Stellar Features

🎯 Distilling Dataset in an Optimization-Free manner. <br> 🎯 The distillation process is Architecture-Free. (Getting over the Cross-Architecture problem.) <br> 🎯 Distilling large-scale datasets (ImageNet-1K) efficiently. <br> 🎯 The distilled datasets are high-quality and versatile. <br>

📚 Introduction

Dataset distillation offers a lightweight synthetic dataset for fast network training with promising test accuracy. We advocate for designing an economical dataset distillation framework that is independent of the matching architectures. With empirical observations, we argue that constraining the consistency of the real and synthetic image spaces will enhance the cross-architecture generalization. Motivated by this, we introduce Dataset Distillation via Disentangled Diffusion Model (D⁴M), an efficient framework for dataset distillation. Compared to architecture-dependent methods, D⁴M employs latent diffusion model to guarantee consistency and incorporates label information into category prototypes. The distilled datasets are versatile, eliminating the need for repeated generation of distinct datasets for various architectures. Through comprehensive experiments, D⁴M demonstrates superior performance and robust generalization, surpassing the SOTA methods across most aspects.

🔧 Quick Start

Create environment

• Python >=3.9
• Pytorch >= 1.12.1
• Torchvision >= 0.13.1

Install Diffusers Library

You can install or upgrade the latest version of Diffusers library according to <a href="https://github.com/huggingface/diffusers">this page</a>.

Modify Diffusers Library

Step 1: Copy the pipeline scripts (<a href="https://github.com/suduo94/D4M/blob/main/scripts/pipeline_stable_diffusion_gen_latents.py">generate latents pipeline</a> and <a href="https://github.com/suduo94/D4M/blob/main/scripts/pipeline_stable_diffusion_latents2img.py">synthesis images pipeline</a>) into the path of Diffusers Library: diffusers/src/diffusers/pipelines/stable_diffusion.

Step 2: Modify Diffusers source code according to <a href="https://github.com/suduo94/D4M/blob/main/scripts/README.md">scripts/README.md</a>.

Generate Prototypes

cd distillation
sh gen_prototype_imgnt.sh

Synthesis Images

cd distillation
sh gen_syn_image_imgnt.sh

Actually, if you don't need the JSON files (prototype) for exploration, you could combine the generate and synthesis processes into one, skipping the I/O steps.

Training-Time Matching (TTM)

cd matching
sh matching.sh

Validate

cd validate
sh train_FKD.sh
