Pruning is a technique used to reduce the complexity of machine learning models, leading to faster inference times and reduced model size. This guide covers various pruning techniques, their applications, and the benefits they offer.
Types of Pruning
Structural Pruning:
- This method involves removing entire neurons or layers from the network.
- It can significantly reduce the model size and computational requirements.
- Learn more about structural pruning.
Filter Pruning:
- In this technique, the weights of the neurons are pruned, rather than the neurons themselves.
- This method is less aggressive compared to structural pruning and preserves the network's structure.
- Explore filter pruning in detail.
Neuron Pruning:
- This method removes individual neurons based on their importance or influence on the output.
- It can lead to a more compact and efficient model.

Benefits of Pruning
- Reduced Model Size: Pruning reduces the number of parameters in the model, leading to smaller file sizes.
- Faster Inference: The reduced model size leads to faster inference times, making it suitable for real-time applications.
- Improved Efficiency: Pruning can improve the energy efficiency of models, making them suitable for battery-powered devices.
