sigmoids
Curves like snakes
Sigmoids are S-shaped curves or structures.
In anatomy, the sigmoid colon is the S-curved section of the large intestine before the rectum.
In mathematics and machine learning, a sigmoid function produces an S-shaped curve that maps any input to a value between 0 and 1, making it useful for probability calculations and neural networks: The model uses sigmoids in its activation layers.
