Synaptic Pruning and Neural Networks

 

Synaptic pruning (aka neural pruning) helps the formation of neural networks. In this post we’ll look to understand the terms “synaptic pruning” and “neural networks.” We’ll also look at how synaptic pruning can help the formation of neural networks. This is new material for IB Psychology “additional terms.”
