In the context of [[artificial neural network]], '''pruning''' is the practice of removing [[Parameter|parameters]] (which may entail removing individual parameters, or parameters in groups such as by [[artificial neurons|neurons]]) from an existing network.<ref>{{cite arXiv|last1=Blalock|first1=Davis|last2=Ortiz|first2=Jose Javier Gonzalez|last3=Frankle|first3=Jonathan|last4=Guttag|first4=John|date=2020-03-06|title=What is the State of Neural Network Pruning?|class=cs.LG|eprint=2003.03033}}</ref> The goal of this process is to maintain accuracy of the network while increasing its [[efficiency]]. This can be done to reduce the [[Computational resource|computational resources]] required to run the neural network.

== Node (neuron) pruning ==
A basic algorithm for pruning is as follows:<ref>Molchanov, P., Tyree, S., Karras, T., Aila, T., & Kautz, J. (2016). ''Pruning convolutional neural networks for resource efficient inference''. arXiv preprint arXiv:1611.06440.</ref><ref>[https://jacobgil.github.io/deeplearning/pruning-deep-learning Pruning deep neural networks to make them fast and small].</ref>
#Evaluate the importance of each neuron.

Recently a highly pruned three layer tree architecture, has achieved a similar success rate to that of LeNet-5 on the CIFAR-10 dataset with a lesser computational complexity.<ref>{{Cite journal |last1=Meir |first1=Yuval |last2=Ben-Noam |first2=Itamar |last3=Tzach |first3=Yarden |last4=Hodassman |first4=Shiri |last5=Kanter |first5=Ido |date=2023-01-30 |title=Learning on tree architectures outperforms a convolutional feedforward network |journal=Scientific Reports |language=en |volume=13 |issue=1 |pages=962 |doi=10.1038/s41598-023-27986-6 |issn=2045-2322 |pmc=9886946 |pmid=36717568}}</ref>
== Edge (weight) pruning ==
Most work on neural network pruning focuses on removing weights, namely, setting their values to zero.
Early work suggested to also change the values of non-pruned weights <ref>{{Cite journal |last=Chechik |first=Gal |last2=Meilijson |first2=Isaac |last3=Ruppin |first3=Eytan |date=2001-04 |title=Effective Neuronal Learning with Ineffective Hebbian Learning Rules |url=https://ieeexplore.ieee.org/abstract/document/6789989 |journal=Neural Computation |volume=13 |issue=4 |pages=817–840 |doi=10.1162/089976601300014367 |issn=0899-7667}}</ref>.
