Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
Explain why artificial neural networks are the most commonly used deep learning models.

### Response:
Artificial neural networks are the most commonly used deep learning models because they are able to approximate non-linear functions. They structure their operations as a network of nodes and can accurately process complex data inputs more accurately than traditional machine learning algorithms. Additionally, they have the ability to self-adjust their parameters, making them better able to understand and learn from complex data.
