Applications in Large Models

Backpropagation

• A perfect embodiment of gradient computation and the chain rule.

Model Training

• The core of minimizing the loss function (an optimization problem); all optimizers (SGD, Adam, RMSProp) are variants of gradient descent.

Activation Functions

• Their derivative properties are critical for gradient propagation.

Model Convergence Analysis

• Involves convergence theory from calculus.
