Gradient Descent

The fundamental optimization algorithm used to train neural networks.

Definition

The fundamental optimization algorithm used to train neural networks. It calculates the direction that reduces the error most quickly and takes a step in that direction. Repeated thousands or millions of times, this gradually finds good weights for the network. The 'learning' in machine learning.
