Myelin
Commonly used in AI, Neural Networks
Myelin, in the context of neural networks and artificial intelligence, is a metaphorical term used to describe the process of insulating or enhancing connections between neurons or nodes. It originates from biology, where myelin refers to the sheath that surrounds nerve fibers, improving the speed and efficiency of electrical signal transmission.
How It Works
In biological systems, myelin is a fatty layer that wraps around the axons of neurons. This insulation allows electrical impulses to jump between gaps in the sheath called Nodes of Ranvier, through a process known as saltatory conduction. This significantly increases the speed at which signals travel along nerve fibers. In artificial neural networks, the term is used metaphorically to describe techniques that strengthen or optimise the connections between nodes, such as weight adjustments or layer enhancements, to improve learning efficiency and processing speed.
