Experiments

Base Comparison between SOTA performance mentioned here

VGG-16 | CIFAR-10 (downsampled->100 images per class)

I had to downsample the dataset for the sake of NTK based scrubbing method computation on 16GB RAM, 8 GB VRAM.

cd sota_method_performance/vgg16_cifar10
chmod +x runner.sh
./runner.sh

CNN | CIFAR-10 (downsampled->100 images per class)

cd sota_method_performance/cnn_cifar10
chmod +x runner.sh
./runner.sh

Weak CNN | CIFAR-10 (downsampled->100 images per class)

cd sota_method_performance/weaker_cnn_cifar10

Effect of Size of Rememberance Sample Dataset (Images Per Class-IPC) over Performance of Unlearning

cd ipc_exp_cifar10

# K=1
cd ipc1
chmod +x runner.sh
./runner.sh

# K=10
cd ipc10
chmod +x runner.sh
./runner.sh

# K=50
cd ipc50
chmod +x runner.sh
./runner.sh

Effect of different K values over different sizes of Forget set (Dataset: CIFAR-10, Model: VGG16)
