9. What is Deep Learning? The Deep learning is a subset of machine learning that involves systems that think and learn like humans using artificial neural networks. The term 'deep' comes from the fact that you can have several layers of neural networks. One of the primary differences between machine learning and deep learning is that feature engineering is done manually in machine learning.
