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.

Factorization

Libraries

Both Tensorflow and PyTorch have built in libraries for pruning:
