🏷️ A Label is Worth A Thousand Images in Dataset Distillation

This repository contains the official code for A Label is Worth A Thousand Images in Dataset Distillation. 📝✨

🛠️ Basic Setup

Make sure the following packages are installed in your environment:

torch==1.13.1  
torchvision==0.14.1  
kornia==0.6.12  
einops==0.6.1  
numpy==1.20.1  
tqdm==4.64.1  
wandb==0.13.8  
scipy==1.10.1

📌 See requirements.txt for an exhaustive list of dependencies.

1️⃣ Generating Experts

First, you need to generate expert models and save intermediate checkpoints. The relevant training scripts can be found in the train_expert folder.

🏋️ Training Expert Model on ImageNet

torchrun --nproc_per_node=1 train.py --model=resnet50 --data-path=/PATH/TO/IMAGENET-1K/datasets/imagenet256 \
  -b=256 --lr=0.0005 --output-dir=/PATH/TO-SAVE/EXPERT/CHECKPOINTS/results_100_S \
  --print-freq=200

🏋️ Training Expert Model on TinyImageNet / CIFAR-10

python buffer.py --dataset=Tiny --model=ConvNet --train_epochs=60 --num_experts=1  \
  --buffer_path=/PATH/TO-SAVE/EXPERT/CHECKPOINTS/results_100_S  --data_path=/PATH/TO/DATASET/data/tiny-imagenet-200 --save_interval 1

2️⃣ Training Student Model with Expert-Generated Soft Labels

python nodistill.py --dataset=CIFAR100 --ipc=50 --expt_type=nothing  --teacher_label  \
  --max_expert_epoch=104 --lr_net=1.e-02  --expert_path=/PATH/TO-YOUR/EXPERT/CHECKPOINTS/results_100_S  \
  --data_path=/PATH/TO/DATASET/cifar100  --student_model=ConvNet \
  --teacher_model=ConvNet --epoch_eval_train 3000

🔑 Key Arguments:

• expt_type: Experiment type

  • nothing: Default. Train a student network using expert labels.
  • tune_start: Sweep through different expert checkpoints to find the best expert epoch.
  • tune_lr: Tune student model learning rate.
  • other: See code for more details.

• teacher_label: Use soft labels generated by the expert (teacher).

• max_expert_epoch: Which expert checkpoint to use (in tune_start mode, this argument indicates the max expert epoch to sweep).

• student_model: Student model architecture.

• teacher_model: Teacher model architecture.

• epoch_eval_train: Number of training epochs for the student network.
