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

Correct Answer: Activation functions introduce non-linearity.

Step 1: Understand that a neural network is a system that tries to learn from data.
Step 2: Know that neural networks use mathematical functions to process information.
Step 3: Realize that many mathematical functions are linear, meaning they create straight lines.
Step 4: Learn that real-world data is often complex and not just straight lines.
Step 5: Understand that an activation function is a special type of function used in neural networks.
Step 6: Know that the main job of an activation function is to add non-linearity to the network.
Step 7: Recognize that by adding non-linearity, the network can learn and recognize complex patterns in the data.
