Neural Network Compression
Brief survey on neural network compression techniques.
Pruning
Sensitivity Methods
The idea here is to measure how sensitive each neuron is.
I.e., if you remove the neuron, how will it change the output?
- Mozer and Smolensky (1988)[1] use a gate for each neuron. Then the sensitivity and be estimated with the derivative w.r.t the gate.
- Karnin [2] estimates the sensitivity by monitoring the change in weight during training.
- LeCun e al. present Optimal Brain Damage [3]
Quantization
There are many works which use 8-bit or 16-bit representations instead of the standard 32-bit floats.
Factorization
Libraries
Both Tensorflow and PyTorch have built in libraries for pruning:
