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.
