ActivationFunction class abstract

The abstract base class (or interface) for all activation functions.

The purpose of this class is to define a common contract that all activation functions, such as ReLU, Sigmoid, or Tanh, must follow.

By having this common interface, layers like DenseLayer can be written to work with any activation function, making the framework modular and easy to extend with new, custom activations.

Example

// Both layers accept an object that implements ActivationFunction.
Layer denseWithReLU = DenseLayer(64, activation: ReLU());
Layer denseWithTanh = DenseLayer(64, activation: Tanh());
