Pruning Deep Neural Networks from a Sparsity Perspective

[ICLR 2023] This is an implementation of Pruning Deep Neural Networks from a Sparsity Perspective

• An illustration of our hypothesis on the relationship between sparsity and compressibility of neural networks.

Requirements

See requirements.txt

Instructions

• Global hyperparameters are configured in config.yml
• Use make.sh to generate run script
• Use make.py to generate exp script
• Use process.py to process exp results
• Experimental setup are listed in make.py
• Hyperparameters can be found at process_control() in utils.py

Examples

• Run make_stats.py to prepare for each dataset
• Train One Shot with FashionMNIST, Linear, $T=30$, 'Global Pruning', $P=0.2$

  python train_classifier.py --control_name FashionMNIST_linear_30_global_os-0.2

• Test Lottery Ticket with CIFAR10, MLP, $T=30$, 'Layer-wise Pruning', $P=0.2$

  python train_classifier.py --control_name CIFAR10_mlp_30_layer_lt-0.2

• Train SAP with CIFAR10, ResNet18, $T=15$, 'Neuron-wise Pruning', $p=0.5$, $q=1.0$, $\eta_r=0.001$, $\gamma=1.2$

  python train_classifier.py --control_name CIFAR10_resnet18_30_neuron_si-0.5-1.0-0.001-1.2

Results

• Results of (a) retrained and (b) pruned models at each pruning iteration for 'Global Pruning' with CIFAR10 and ResNet18.
