## Understanding Neural Networks
Neural networks mimic the structure and functionality of the human brain, consisting of interconnected nodes (neurons) organized into layers. These networks learn from data patterns to make predictions, classify inputs, and perform various tasks.
### Key Components
1. **Input Layer:**
Receives input data and passes it to the network.
2. **Hidden Layers:**
Intermediate layers where data is processed through weighted connections and activation functions.
3. **Output Layer:**
Produces the final output or prediction based on the processed data.
