Question: What is the primary function of an activation function in a neural network?

Options:

Correct Answer: To introduce non-linearity

Solution:

Activation functions introduce non-linearity into the model, allowing it to learn complex patterns.

What is the primary function of an activation function in a neural network?

Step 1: Understand that a neural network is a model that learns from data.
Step 2: Know that the model makes predictions based on input data.
Step 3: Realize that without activation functions, the model can only learn simple patterns (like straight lines).
Step 4: Learn that activation functions add non-linearity, which means the model can learn more complex patterns (like curves).
Step 5: Conclude that the primary function of an activation function is to help the model learn these complex patterns.
