HAP is an advanced structured pruning library written for PyTorch. HAP prunes channels based on their second-order sensitivity. Channels are sorted based on this metric, and only insensitive channels are pruned. In the Neural Implant method, channels with moderate sensitivity levels are replaced with a trainable implant.

• PyTorch version >= 1.4.0
• Python version >= 3.6
• To install HAP and develop locally:

git clone https://github.com/yaozhewei/HAP

• Then run

bash install.sh

1. Pretraining:

   # for pretraining CIFAR10
   $ python main_pretrain.py --learning_rate 0.1 --weight_decay 0.0002 --dataset cifar10 --epoch 200

2. Testing without Neural Implant on CIFAR10

   python main_prune.py --network resnet --depth 56 --dataset cifar10 --batch-size 64 --learning-rate 0.02 --weight-decay 4e-4 --ratio 0.5 --use-decompose 0 --gpu "0"

• Hessian-Aware Pruning and Optimal Neural Implant
